INTRODUCTION
Betanal maxxPro is a selective weedkiller for the post-emergence control of many annual weeds in beet crops. Betanal maxxPro is recommended for low volume overall spraying in a planned spray programme and can follow an Approved pre-emergence herbicide and / or Approved post-emergence herbicide treatment(s) used at recommended low doses for programmes. Betanal maxxPro acts mainly by contact action but will, in a planned programme and in moist conditions, provide residual control of some later germinating weeds.

WEEDS CONTROLLED
The recommended timing of application is fully expanded cotyledon stage of the largest weed present and this should be followed wherever possible. The weed growth stage given below is for an occasional larger weed which will usually be controlled from a full programme of Betanal maxxPro sprays.
Weeds killed up to 6 expanded true leaves - Common field-speedwell, Fat-hen, Wild Radish, (Runch).
Weeds killed up to 4 expanded true leaves - Annual meadow-grass, Black-bindweed, Common fumitory, Field pansy, Field penny-cress, Ivy-leaved speedwell.
Weeds killed up to 2 expanded true leaves - Black nightshade, Corn marigold, Groundsel, Henbit dead-nettle, Knotgrass, Pale persicaria, Red dead-nettle, Redshank, Scarlet pimpernel, Small nettle.
Weeds killed at cotyledon stage - Bugloss Charlock Common orache, Volunteer oilseed rape, Crane’s-bill (Qualified minor use recommendation), Corn spurrey (Qualified minor use recommendation).
Other weeds controlled - Cleavers - killed up to 5 cm across or high. Common chickweed - killed up to 10 cm across or high. Mayweed - severe check or kill up to 2.5 cm across or high.

CROP INFORMATION
All commercially grown varieties of sugar beet, fodder beet and mangels may be treated with Betanal maxxPro.
Soil
Betanal maxxPro may be used on all soil types. On soils with more than 5% organic matter content residual activity may be reduced.
Factors Affecting Crop Tolerance
When used as recommended, Betanal MaxxPro exhibits good safety to beet. Several factors may affect crop tolerance and individually may appear to have little effect, but may be important when two or more occur at the same time.
Drift
Avoid drift to areas outside those being sprayed, having due regard to the prevailing weather conditions and spray quality being used. The risk of drift is greater when a FINE quality spray, as recommended for this product, is used.
Rates of use
A programme of Betanal MaxxPro low volume treatments should be applied as directed below.
1st spray
Crop and weeds at cotyledon stage 1.25 L/ha
2nd and subsequent sprays
Crop at or beyond two true leaf stage 1.5 L/ha
Timing
Crop: The first Betanal maxxPro application may be made when the majority of crop plants have reached the fully expanded cotyledon stage.
Weeds: The first flush of weeds should preferably not be larger than the fully expanded cotyledon stage at the time of spraying and must not be larger than the sizes stated under WEEDS CONTROLLED. Where a pre-emergence treatment has been applied as a band spray, it will be necessary to time the first post-emergence Betanal maxxPro treatment according to the size of weeds present between the rows where there is no pre-emergence effect. A single application of Betanal maxxPro is seldom sufficient to achieve season long weed control. Susceptible weeds may not all be killed by the first treatment. They will usually be checked and then controlled by later applications. Further Betanal maxxPro sprays should be applied as each new flush of weeds reaches the cotyledon stage. Successful results from a programme are achieved by applying each spray when the previous one is still showing an effect on the weeds, but a minimum of 5 days must elapse between treatments.

Volume 80 to 200 litres water per hectare. Spray operations and Spray Quality.

COMPATIBILITY AND SEQUENCES
Compatibility
Betanal maxxPro is compatible with: Goltix WG
Betanal MaxxPro plus Goltix WG
For improved residual activity Goltix WG may be added to Betanal maxxPro applications in a postemergence programme. Dose: Betanal maxxPro 1.25 L/ha. Plus Goltix WG 1 kg/ha. Goltix WG should be thoroughly dispersed in the spray tank one third full of water before adding Betanal maxxPro and filling to the mark. Continue agitation whilst spraying.
Timing
As for Betanal maxxPro alone. These mixtures may be used up to three times in the crop (Do not exceed maximum total dose allowed for partner products).
Sequences. After seed treatments:- Betanal maxxPro may be used as part of a planned programme after the use of approved seed treatments containing clothianidin (Poncho® Beta) or imidacloprid.
Programmes with pre-emergence treatments:- Betanal maxxPro may be used as part of a planned programme after the use of approved preemergence treatments at recommended doses for programmes.
Programmes with post-emergence treatments for broad-leaved weeds:- See crop tolerance section below.
Sequences with grass weedkillers:- Betanal maxxPro may be used in sequence with grass weedkillers. Refer to graminicide product literature for recommended intervals.
SUCCEEDING CROPS
Beet crops may be sown at any time after the use of Betanal maxxPro. Any other crop may be sown 3 months after using Betanal maxxPro. Ploughing (mould board) to a minimum depth of 15 cm should precede preparation of a new seed bed.

COMPANY ADVISORY INFORMATION
Crop Tolerance
Several factors may affect the crop tolerance and performance of Betanal maxxPro especially when used in mixtures. Some transient crop effects may occur soon after application but when the crop is under stress, application of Betanal maxxPro can lead to crop check from which it may not fully recover. In extreme cases some loss of crop may occur. Application of Betanal maxxPro or Betanal maxxPro mixtures is not recommended when the crop is suffering from stress. Stress can be caused by a number of circumstances, the most important of which are as follows.
Use after other Herbicides
Most beet crops are treated with more than one herbicide. In these circumstances it is not always possible to predict the interactions which may occur, and the effects of stresses in such conditions may be more severe.
Manganese Deficiency
If a crop is suffering from manganese deficiency it may be checked by Betanal maxxPro. To avoid crop check, manganese should ideally be applied to the crop first.
Lime Deficiency
Crops suffering from lime deficiency may be checked when sprayed with Betanal maxxPro. Growers should ensure that the lime status of the soil is satisfactory before drilling.
High Temperatures
When the temperature is, or is likely to be, above 21°C (70°F) on the day of spraying, application of Betanal maxxPro should be made after 5 pm otherwise crop check may occur. If crops are subjected to substantial day to night temperature changes shortly before or after spraying, a check may occur from which the crop may not fully recover.
Frost
Crops sprayed with Betanal maxxPro and subjected to frost within seven days may be checked such that they may not fully recover.
High Light Intensity
Where the crop is already under stress, and Betanal maxxPro is sprayed in conditions of high light intensity, the crop may suffer a check from which it may not fully recover.
Wind
Strong winds can damage crops by physical buffeting and contingent damage can arise from blown soil particles. When wind damage has occurred, delay application of Betanal maxxPro until the crop has recovered.
Insect
Attack If the crop is damaged by insects, eg mangel fly, pygmy mangel beetle or flea beetle, Betanal maxxPro may cause a check from which the crop may not fully recover.
RESISTANCE
Certain weeds may develop resistance to Bayer products. Since such circumstances are beyond our control, Bayer CropScience will be under no liability for any resulting loss or damage whatsoever.
