- Do not use bentazone on:-
• Soils with shallow groundwater (<1m below surface);
• Soils on chalk other limestone that are shallow (30-35cms) and stony (>10% of surface area);
• Soils with low organic content (1% OC).
Do not use bentazone before 1 April.
Reduce dose rates to ≤1000g bentazone/ha/year (Basagran SG:≤1.15 kg/ha/year).
Use a 6m grass buffer strip or a 5m no-spray zone adjacent to watercourses.
  
DIRECTIONS FOR USE 
IMPORTANT: This information is approved as part of the Product Label. All instructions within this section must be read carefully in order to obtain safe and successful use of this product.
Basagran SG is herbicide for post‑emergence broad‑leaved weed control in spring and winter field beans, broad, dwarf French, navy and runner beans, peas, linseed, narcissi and potatoes. 
Restrictions/Warnings
Weed control
The best weed control will be achieved if crops are sprayed when weeds are small and actively growing, provided the crop is within the correct growth stages, see below.
It is essential to achieve full cover of all weed surface areas, especially the growing point. Therefore adjust spray volumes and pressures according to the size and density of the weed populations and crop cover.
It is preferable to use the split dose if conditions are likely to be very warm, sunny or humid, if foliage is tender or if a sensitive variety is to be treated (see Section 4.2).
Only single applications are approved for use in peas.
Where weeds classed as moderately susceptible form an important part of the weed population, the split dose will only give acceptable control if the weeds are cotyledon only. If true leaves are present, a single application of 1.65 kg/ hectare should be made.
The addition of Actipron, Adder or Cropspray 11E is recommended only in dwarf green beans and potatoes to improve control of fat‑hen, particularly when dry conditions are prevalent. Enhanced control of other weeds listed as susceptible may also be achieved.
Sequences/Tank mixes
Sequence with other spray chemicals:
Do not apply insecticides within 7 days of treatment with Basagran SG. Basagran SG BEFORE a post‑emergence grass herbicide:‑ leave an interval of at least 7 days between treatments. Basagran SG AFTER a post‑emergence grass herbicide:‑ leave an interval of 14 days and carry out a leaf wax test where relevant.
Other than the permitted mixtures in the relevant crops, do not tank mix Basagran SG with any other products.
Weather conditions
Do not apply Basagran SG or any of the recommended mixtures to any crop that may have been subjected to stress conditions, such as herbicide or disease injury, excessive acidity/alkalinity, trace element deficiency, drought, waterlogging, widely fluctuating temperatures, or physical damage to the foliage as caused by abnormal wind, rain, hail or frost.
Do not spray under HOT SUNNY CONDITIONS when temperatures are at or above 21°C, particularly during the mid‑day period.
When the above conditions occur, spraying should be delayed until the evening. This is particularly important when there has been a change to hot sunny weather following a cool cloudy period.
Do not spray if rain or frost is expected, nor if the foliage is wet.
A minimum period of 6 hours free from rain is required after application.
Do not apply Basagran SG during periods of drought or unseasonably cold weather as unsatisfactory weed control may result.
Crops
Check varietal tolerance of varieties before using.
A satisfactory leaf wax test using crystal violet marker dye, must be carried out before applying Basagran SG or the recommended mixtures to peas.
DO NOT treat forage pea varieties or mange‑tout.
Do not use on first early or seed crop potatoes.
Restrictions relating to certain varieties of potatoes should be strictly observed.
Check also all specific restrictions and warnings relevant to potatoes.
CONSULT PROCESSORS BEFORE USE.
Application
Do not overlap spray swaths.
Avoid spray drift onto neighbouring crops, particularly lettuce and sugar beet.
The recommended water volume is 100‑450 litres/hectare. The lowest volume of 100 litres/hectare can only be used when weeds are no larger than cotyledon stage , weed density is low to moderate and crop shielding is negligible.
WASH EQUIPMENT thoroughly immediately after use. Fill the tank with clean water and leave overnight. Spray out before storage or using other products. Traces of the product may cause damage to susceptible crops sprayed later.
 
Crops  
DWARF FRENCH, NAVY AND RUNNER BEANS
Time of Application
Apply Basagran SG in runner beans when the crop has between one and two trifoliate leaves and in dwarf French and navy beans as soon as the crop has two trifoliate leaves.
Crop selectivity is partly dependent on adequate leaf wax formation. When conditions which reduce leaf wax occur the application should be delayed by at least 5 to 7 days to await recovery.
Basagran SG may cause transient scorch, which can be prolonged with applications later than the three trifoliate leaf stage
Method of Application:
Basagran SG can be applied either by a conventional single dose or preferably by a split dose treatment.

SPRING AND WINTER FIELD BEANS AND BROAD BEANS
Basagran SG can be used alone or following a pre‑emergence herbicide providing the crop is not adversely affected. Crop selectivity is partly dependent on adequate leaf wax formation. Frost, wet conditions, physical damage, disease or previous sprays can all reduce leaf wax and when this occurs application should be delayed by at least 5 to 7 days to await recovery
Methods of Application:
Basagran SG can be applied either by a conventional single dose or by a split dose treatment. The correct crop and weed growth stages are given in the following table. 
The single dose is usually the preferred treatment for the winter bean crop due to overwintered weeds being more advanced.
The split dose is the preferred method in spring field beans provided that the weed and crop stage are suitable.
  Rates and Timing :
Crop: Spring Beans and Broad Beans
Application method:Split dose:(a)
                            Single(b) dose
Rate kg/hectare:0.85 kg/ha followed by 0.85 kg/ha OR 1.1 kg/ha followed by 0.55 kg/ha
                          1.65 kg/ha
Crop stage (see diagram):2 to 6 leaf pairs, max.height 15 cm/Optimum crop stage is 5 10 cm;
                                         3 to 6 leaf pairs, max. height 15 cm Broad Beans: 3 to 4 leaf pairs only. Optimum stage for both crops - as for split dose
Weed stage: cotyledon to 2 leaves only. (optimum cotyledon).
                     cotyledon to 6 leaves. (optimum 2 leaf)
 
Crop: Winter Beans (applied in the spring)
Application method:Split dose
                                Single dose
Rate kg/hectare:0.85 kg/ha followed by 0.85 kg/ha OR 1.1 kg/ha followed by 0.55 kg/ha
                          1.65 kg/ha
Crop stage (see diagram):2 leaf pairs up to and including 7 leaf pair stage Optimum crop stage is 5 to 15 cm ;
3 leaf pairs up to and including 7 leaf pair stage Optimum stage - as for split dose.

Weed stage: cotyledon to 2 leaves only. (optimum cotyledon). cotyledon to 6 leaves. (optimum 2 leaf).

Important notes:
(a) If conditions are conducive to increased herbicide activity and crop scorch, e.g. warm sunny conditions, tender foliage or a more sensitive variety, then the 0.85/0.85 kg/hectare split should be used.
(b) Broad beans are more sensitive than field beans. The split dose treatment is always preferable to the single dose in this crop.

 Use only the split dose treatments on these varieties. Processors must be consulted before use in broad beans.
Crop Effects ‑ Field and Broad Beans
Slight crop scorch can occur after spraying. This is seen as a blackening of leaf margins, particularly on older leaves - all subsequent new leaves being unaffected. A temporary vigour check may also occur under some conditions. These effects generally have no influence on yield. They can, however, be more pronounced when applications are made beyond the optimum growth stage, particularly when the single dose is used and/or adverse weather conditions prevail.
Warnings
Avoid overlapping spray bouts and do not add Actipron, Adder or Cropspray 11E to Basagran SG in field and broad bean crops. Do not apply on crops earlier than the 2 leaf pair stage, or crops more than 15 cm tall (except winter beans) or if flower buds are visible.
PEAS:
Basagran SG may be used alone or in mixtures with Tropotox. The choice of treatment depends on the weed spectrum to be controlled .
Basagran SG, or the above mixtures may be used following pre-emergence broad-leaf herbicides provided that the crop is undamaged and showing no adverse symptoms of herbicide application. Avoid application to crops which are under stress from physical damage or disease, or other factors.
A satisfactory leaf wax test using crystal violet marker dye must be performed before applying Basagran SG or Basagran SG mixtures, particularly with early drillings which tend to have less leaf wax. Slight scorch of the leaf margins and/or hormonal twisting may occur shortly after spraying but the crop will soon recover; yield and maturity will not be adversely affected.
Time of Application
Apply Basagran SG, Basagran SG + Tropotox from when the peas have three nodes (3 fully expanded leaves) until before the flower buds can be found enclosed in the terminal shoot. The optimum timing is when the majority of weeds have germinated, but are still at the seedling stage
Rate of Application
(Basagran SG alone - Apply 1.65 kg/ha
Basagran SG + Tropotox tank mix - Apply 1.65 kg/ha Basagran SG + 3.75 l/ha Tropotox
NOTE: Only single applications are approved for use in peas.

(* Particular care should be taken to ensure treating these early maturing varieties at the correct growth stage, because they flower at an earlier node than later‑maturing varieties. They should not be treated after the fifth expanded leaf stage. † Picking pea varieties. Bold type denotes varieties that are slightly sensitive. Slight scorch may result from treatment with Basagran SG + Tropotox.)
DO NOT treat the varieties Carouby de Mausanne, Conquest, Danielle, Dinos, Filby, Fonado, Printana, Sherbourne, Turon, Santa or Vedette.
DO NOT treat forage pea varieties or mange-tout. For the approval status and tolerance of any variety not mentioned above, consult your local BASF representative or the Processors and Growers Research Organisation.
LINSEED:
Since linseed offers poor weed competition, weed control is important, especially in the early growth stages.
Basagran SG may be used alone or following pre-emergence herbicides, provided that the crop is showing no adverse symptoms.
Time of Application:
Apply when the crop is between 2½‑30 cm tall, but before the flower buds are visible
The optimum timing is when the majority of weeds have germinated and are still in the seedling stage. As a guide, this is usually when the crop is between 7½-20 cm tall.
Methods of Application:
Basagran SG can be applied either by a conventional single dose or by a split dose treatment.
POTATOES:
Basagran SG is a post-emergence treatment for use in maincrop and second early potatoes. It may be used alone or following a pre-emergence herbicide in a programme of weed control provided the crop is undamaged and showing no adverse symptoms of herbicide application. Basagran SG used in sequence with a pre-emergence application of metribuzin gives improved weed control from the combination of residual and contact activity. DO NOT apply following a post-emergence application of metribuzin (Sencorex WG).
Some leaf‑yellowing or slight scorch may occur under certain conditions (see ‘Varietal Tolerances’ and ‘Factors Affecting Crop Tolerance’). These effects are transient, only being present on leaves exposed to the spray. All subsequent growth is unaffected and yields are not adversely affected, provided that applications are within the following guidelines.
Do not irrigate for at least 24 hours following application. In dry conditions irrigation prior to Basagran SG application can be beneficial to ensure that weeds are actively growing. However, foliage must be dry before application.
Avoid overlapping spray bouts.
Potatoes- Basagran SG alone
Time of Application:
Apply Basagran SG when the majority of weeds have emerged and are at the cotyledon to seedling stage, but before most of the crop has reached a height of 15 cm. Application when the crop is taller than 15 cm is not recommended because foliage scorch can be increased leading to a possible check to the crop vigour and yields. Weeds can also be shielded from the spray by crop foliage with later applications. Methods of Application Basagran SG can be applied either by a conventional single dose or preferably by a split dose treatment. See Section 4.2, Application.
Potatoes- Basagran SG/Sencorex sequences:
Apply 1.0 kg/ha metribuzin (Sencorex WG) pre-emergence of the potatoes as recommended in the metribuzin label. On soils with high organic matter content, better activity can be achieved by pre- or post-planting incorporation or by application pre-final ridging. Follow this with an application of 0.85 kg/ha Basagran SG + 1.5 L/ha Actipron post-crop emergence when the weeds are at cotyledon to 2 leaf stage, but before the potato shoots exceed 15 cm in height. Check varietal restrictions for Basagran SG and metribuzin before embarking on this programme
Potatoes- Varietal Tolerances:
The following maincrop and second early varieties can be treated either with Basagran SG alone or, if required, with the addition of Actipron, Adder or Cropspray 11E:

(+ second early varieties 0 Do not use the Sencorex WG/Basagran SG sequence on this variety. * These varieties have shown more foliage scorch than others. Particular attention should be paid to the crop stage and factors affecting crop tolerance. Do not use the single dose treatment with permitted adjuvants on these varieties. # These varieties are recommended on the basis of limited (2 years) data.)
DO NOT treat the following varieties: Bintje, Fianna, Lady Rosetta, Morag, Morene, Rode Pipo, Russett Burbank, Sante, Shepody, Stemster and Stroma.
DO NOT treat seed crops or first early varieties.
Factors Affecting Crop Tolerance:
Basagran SG should not be applied to potatoes under hot, sunny conditions when temperatures are at or above 21°C, particularly during the mid-day period. When these conditions are encountered, spraying should be delayed until evening. It should be noted that in general, crop foliage is more sensitive when there is a sudden change to hot, sunny weather following a cool, cloudy period. This sensitivity diminishes after approximately three days.
Crop tolerance will also be reduced if the crop is under stress, e.g. from such factors as physical damage (as from high wind), heavy rain or hail, virus diseases, blackleg, nematodes, Rhizoctonia, excessive soil alkalinity or acidity, or frost either shortly before or after treatment. Wet foliage is prone to scorch by Basagran SG.
MIXING AND SPRAYING:
 Mixing
Half fill the spray tank with clean water and start the agitation. Pour in the required amount of Basagran SG. Add the remainder of the water and continue agitation until spraying is completed. When tank mixes are to be used, each product should be added separately to the spray tank.
Application
All applications should be made as a FINE spray, as defined by BCPC, unless the highest water volumes are used when FINE or MEDIUM sprays are permissible. It is essential to achieve full cover of all weed surface areas, especially the growing point. Therefore ADJUST SPRAY VOLUMES AND PRESSURES ACCORDING TO THE SIZE AND DENSITY OF THE WEED POPULATIONS AND CROP COVER.
