MISSION 200 SL is a water soluble concentrate containing 200 g/l Diquat as the dibromide salt. Diquat is a non-residual bipyridyl contact herbicide and crop desiccant.

DIRECTIONS FOR USE
MISSION 200 SL is a water soluble concentrate containing 200 g/litre Diquat as the dibromide salt. Diquat is a non-residual bipyridyl contact herbicide and crop desiccant.
MISSION 200 SL can be used as a desiccant (pre harvest) in potatoes, oilseed rape, combining peas (harvested dry), field beans (animal feed), barley and oats for animal feed, linseed. It can also be used for control of broad-leaved weeds in all crops (edible and non-edible) before emergence and all inter-row crops after emergence.
The product acts rapidly on green parts of plants and is rainfast in 15 minutes. In contact with soil, the active substance is rapidly inactivated.
Extreme care should be taken to avoid spray drift as this can severely damage neighbouring crops or plants.

Restrictions
Do not apply potato haulm destruction when the soil is dry. Tubers may be damaged if spray is applied during or shortly after dry periods. Do not add wetters to desiccant sprays for potatoes. Consult processor before adding a wetter when treating peas. The addition of a wetter may increase staining. Do not use on barley, oats and field beans intended for human consumption. When used as an overall spray in sugar beet and edible and non edible crops grown on sandy or peat soils, allow 3 days between application and expected crop emergence or transplanting

Weeds controlled
MISSION 200 SL can be used for the desiccation of potato haulm, oilseed rape, combining peas for harvesting dry, field beans for animal feed, barley and oats for animal feed and linseed. It can also be used for weeds control in all crops (edible and non-edible) pre-emergence and all inter-row crops after emergence. Weeds controlled are: black bindweed, poppy, sow thistle and common chickweed (up to 4 leaf stage in each case).

CROP SPECIFIC INFORMATION
POTATO DESICCATION
MISSION 200 SL can be used for the desiccation of potato haulm. The application should be made when the tubers have the desired size. If potato tubers are to be stored, leave 14 days after treatment before lifting. Best results are achieved by spraying in bright light and under low humidity conditions. Re-growth may occur if seed crops are desiccated early. Do not add a wetter.
Rate of use: 4 litres/ha
MISSION 200 SL may be applied to the potato crop at 2 litres/ha for weed control (see section on weed control in row crops) and up to a maximum of 4 litres/ ha per application for haulm desiccation.
The total dose must not exceed 5 litres/ha

Water volume: Apply in 200-500 litres/ha. Use the higher water volume when the crop is dense

Special note regarding application during or shortly after dry period

Haulm destroyers may damage tubers if applied during or shortly after dry periods. Dry periods are defined as periods when soil moisture deficits, calculated by the MORECS scale are greater than 33-83 mm according to soil and crop type

Do not spray when soil is dry. When mist, light rain or heavy dew is present or imminent, the risk of damage is increased.
On medium, heavy and organic soils, crops may be sprayed if 13 mm of rain has fallen or the equivalent amount of irrigation has been applied in the previous five days and the soil around the tubers is moist.
On sands, light and stony soils, crops may be sprayed if 13 mm of rain has fallen or the equivalent amount of irrigation has been applied in the previous two days and the soil around the tubers is moist.
Soil moisture must be assessed in the field to ensure that the rainfall or irrigation has penetrated to below tuber depth. All parts of the field must comply with this requirement, particularly where soils vary within the field.

DESICCATION OF OTHER CROPS BEFORE HARVEST MISSION
200 SL should be applied when the crops are mature or approaching maturity. If MISSION is applied too early, this will result in immature seed with poor germination and low weight. MISSION will not speed up crop maturity.
Maximum number of treatments: one per crop.

Oilseed rape
Apply MISSION 200 SL when the seed colour on most plants is as follows: Top third: More than half the seeds are green, firm and pliable with a few seeds brown to black. Middle third: 90% of seeds are red-brown to darkbrown with a few black. Remaining 10% of seeds are green but are firm and pliable. Bottom third: All seeds are dark-brown to black.
This is usually 2-3 days later than windrowing would normally have started. In crops which are leaning over, the seeds on the upper side of the stem will mature ahead of those shaded from the sunlight. In this situation, spray when all the seeds in the exposed pods have turned red-brown to dark-brown. Do not wait for all the shaded seeds to ripen.
Do not apply when the crop is immature or past the recommended stage. Avoid desiccation on thin, standing crops and on exposed sites.

Rate of use: 3 litres/ha. Add an alcohol ethoxylate adjuvant in accordance with the manufacturer’s instructions.

Water volume: Apply in 250-500 litres/ha. Use the higher water volume when the crop is dense.

Harvest: Harvest can take place 7-10 days after application. Moisture content of the seeds should be checked first.

Combining peas (harvested dry)
Apply MISSION 200 SL when the crop is mature, which is when the crop starts to show an overall yellow colour (moisture content of peas is 45 % or less).
Top pods: Pods are fleshy, slightly pitted and green, or starting to turn yellow. Seed splits if squeezed. Middle pods: Pods are yellow, crinkled and becoming dry. Seeds are rubbery and can be squeezed without splitting.
Bottom pods: Pods are yellow/brown and paper-thin. Seeds are quite hard.
Earlier treatment may result in a proportion of shrivelled peas from immature pods, thus lowering yields. In addition the crop will take longer to dry out so that some of the advantage of desiccation is lost. There is also a risk of haulm collapse.
If treatment is too late, there is a danger that some bottom pods will shatter.
Where crops are to be used as animal feed, add an alcohol ethoxylate adjuvant in accordance with the manufacturer’s instructions. On peas for processing for human consumption, consult your processor before adding any adjuvant or wetter.

Rate of use: 2-3 litres/ha

Water volume: 200-500 litres/ha. Use the higher water volume when the crop is dense.

Harvest: Harvest can take place as soon as desiccation is complete, which is normally 7-10 days after application.

Field beans
Treated field beans may be used for pigeon and animal feed only. Apply MISSION when the crop is mature, which is when the majority of the crop has turned black.

Rate of use: 3 litres/ha. Add an alcohol ethoxylate adjuvant in accordance with the manufacturer’s instructions.

Water volume: 200-500 litres/ha.

Harvest: Harvest can take place 4-7 days after application.

Laid barley and oats (for animal feed)
Treated laid barley and oats may only be used for animal feed. MISSION should be applied when the crop is mature for harvesting.

Rate of use: 2-4 litres/ha. Add an alcohol ethoxylate adjuvant in accordance with the manufacturer’s instructions

Water volume: Apply in 200-500 litres/ha

Harvest: Harvest can take place as soon as desiccation is complete, which is normally 4-7 days after application. Treated grain and straw may be safely fed to livestock from four days after spraying. A delay in harvest may cause re-growth of grass weeds.

Linseed
Apply MISSION 200 SL when the seed is matured evenly over the whole field, which is when the seed capsules are dark brown and the seed light brown: the seed should rattle in the bolls and ideally the most mature stems should have started to turn yellow just below the capsule cluster.

Rate of use: 3 litres/ha. Add an alcohol ethoxylate adjuvant in accordance with the manufacturer’s instructions.

Water volume: 300-500 litres/ha

Harvest: Harvest can take place 10-20 days after application, when the seed moisture is below 14 %

WEED CONTROL
IN ALL CROPS MISSION can be used to control weeds. Weeds controlled are: black bindweed, poppy, sow thistle and common chickweed (up to 4 leaf stage in each case). The product can be used as an overall spray, or as an inter-row spray. Add an alcohol ethoxylate adjuvant in accordance with the manufacturer’s instructions.

Overall spraying
All crops (edible and non-edible) can be treated before crop emergence or before transplanting. On sandy or peat soils allow three days between spraying and expected crop emergence or transplanting. Early crop potatoes should be treated up to 10% emergence, main crop potatoes should be treated up to 40% emergence, provided that the plant is no more than 15 cm high. Do not apply after emergence under very hot dry conditions or to crops growing from diseased seed or from very small tubers.

Inter-row spraying
Application of MISSION 200 SL after the crop has emerged should be made using a spray guard to avoid contact with the crop foliage. Best results are achieved when MISSION is applied to seedling weeds.

Rate of use: 1.5-2 litres/ha (15-20 ml/100 m2 ).

Water volume: 200-500 litres/ha. When using a knapsack sprayer use 2-5 litres water per 100 m2 . Use the higher water volume when weeds are dense or when weeds are beyond the seedling stage.

Resistance
Diquat (and paraquat) belong to the class of herbicides known as bipyridyls. Strains of Annual Meadow-grass and American Willowherb resistant to paraquat have been found in some hop yards/ gardens and also top and soft fruit orchards. Where paraquat resistant strains are present MISSION may not give full control of these weeds.

Following crops
Any crop may be sown following the application of MISSION 200 SL.

Mixing and spraying
MISSION 200 SL should be applied using a tractor mounted sprayer or a knapsack sprayer. Use as a ‘Medium Quality Spray’ (as defined by the BCPC). When using a knapsack sprayer use 2-5 litres water per 100 m2 Check and clean all hoses, nozzles and equipment to be used prior to use. Fill the sprayer tank for 90% with clean water. Begin agitation and add the required quantity of MISSION to the sprayer tank. Fill the spray tank with water as required whilst agitating. Continue agitating during spraying.
On emptying the container, RINSE CONTAINER THOROUGHLY by using an integrated pressure rinsing device or manually rinsing three times. Add washings to sprayer at time of filling and dispose of container safely. Do not leave spray liquid in the sprayer for long periods (eg. during meals or overnight). At the end of spraying wash sprayer tank, pump and hoses with water and liquid detergent and empty completely.

Compatibility
For the following applications, MISSION 200 SL can be used in tank mix with an alcohol ethoxylate adjuvant, in accordance with the manufacturer’s instructions: desiccation of oilseed rape, laid barley and oats, field beans, linseed and for weed control in row crops. Consult your processor before using an adjuvant on peas for processing for human consumption. DO NOT USE an adjuvant for desiccation of potato haulm
