Suspension concentrate formulation containing 330 g/l terbuthylazine and 70g/l mesotrione.
PROPERTIES OF FARMCO MAIZE
FARMCO MAIZE contains mesotrione and terbuthylazine. The uptake is through both the leaves and the root system, thus combining contact with residual weed control. The product controls a broad spectrum of annual broadleaved weeds and certain grasses. Young weeds are most susceptible to FARMCO MAIZE.
For use only as a herbicide for the control of weeds in forage and grain maize.
Forage and grain maize may be sprayed any time from the two to eight leaves stage.
DO NOT USE on seed crops or on sweet corn varieties.
Always inspect crop and weed growth stage immediately before spraying.
For best results treat young weed seedlings. See weed control tables for application details.
For the best results FARMCO MAIZE should be applied when the weeds are actively growing i.e. in warm humid weather with adequate soil moisture. Treatment in poor growing conditions or in dry soil may give less reliable control.
Do not spray when the crop foliage is wet.
It is not recommended to spray crops suffering stress e.g. when in very cold or drought conditions, or when wide temperature are expected or excessive rainfall is expected to follow application. Under these adverse conditions mild to mode rate chlorosis may be observed on sprayed leaves. This effect is usually transient and does not affect yield.
Take extreme care to avoid drift onto all plants outside the target area, otherwise damage will result.
Ensure that spray swaths are matched accurately and do not overlap.
WEED CONTROL–RATE OF USE
FARMCO MAIZE contains an adjuvant system and the addition of an adjuvant or a tank mix wetting agent is not recommended.
The recommended dose rate is 1.0 to 1.5 litres per hectare depending on the type of weeds present. FARMCO MAIZE should be applied after crop emergence, the preferred forage and grain maize crop stage is when 2-6 leaves have been formed.
Good spray cover is essential and care should be taken to ensure that the sprayer has a matched set of nozzles, the machine is correctly calibrated and adjusted to the correct height above the crop.
Preparation of the spray
Shake the FARMCO MAIZE container before opening.
Half-fill the spray tank with clean water, add the required amount of FARMCO MAIZE and agitate while filing the tank. RINSE CONTAINER THOROUGHLY by using an integrated pressure rinsing device or manually rinsing 3 times. Add washings to sprayer at time of filing and dispose of container safely. Continue agitation during spraying.
Volume of water
Even cover of the weeds is essential.
Use 200 to 300litres (maximum) of water per hectare. The lower rate is preferable but the higher volume may be necessary where there are dense or well developed weed populations.
Apply through a conventional field crop sprayer using a pressure of 2-3 bars. Ensure the sprayer is correctly calibrated before use.
Do not leave a spray liquid in the sprayer for long periods (i.e. overnight).
Apply using a medium equipment spray (BCPC) at a pressure of at least 2 bar. Apply through conventional crop spraying equipment.
It is important to wash equipment thoroughly after use to remove all traces of FARMCO MAIZE as even small amounts may cause damage to crops. Rinse inside of tank with clean water using at least one tenth of the spray tank volume. After flushing through pump and spray lines, drain and repeat procedure.
Disposal of spray tank washings should be in accordance with local, state or national legislation.
Perform superficial cleaning of spray equipment in the field. Application liquids and their residues, products and their residues, emptied containers or packs as well as cleaning and rinsing fluids must not be allowed to enter the water. This also applies to indirect introduction through the sewage system, farmyard and road drains or rainwater and wastewater pipes.
FOLLOWING CROPS AND RECULTIVATION
Ploughing is recommended prior to reseeding. Some slight crop may be seen soon after emergence, but these are usually transitory in nature Forage and grain maize can be reseeded in case of crop failure.
Winter wheat (including durum wheat), winter barley and rye grass can follow a forage and grain maize crop treated with FARMCO MAIZE.
Deep ploughing (greater than 15cm) followed by cultivation is necessary before drilling oilseed rape.
Forage and grain maize, ryegrass, spring wheat and spring barley may be sown in the spring following application of FARMCO MAIZE. Do not sow spinach. Sugar and fodder beets, peas, beans, lettuce and cabbages in the year following the application of mesotrione.
WEAR SUITABLE PROTECTIVE GLOVES when handling the concentrate.
DO NOT CONTAMINATE SURFACE WATERS OR DITCHES with chemical or used
Storage and disposal
KEEP IN ORIGINAL CONTAINER, tightly closed, in a safe place.
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 safely.
DO NOT RE-USE CONTAINER FOR ANY PURPOSE.
Treatment must not be applied on sands or very light soils.
Residual weed control will be reduced on soils with more than 10% organic matter.
FARMCO MAIZE contains two active ingredients with different modes of action.
Mesotrione is a triketone which disrupts development of plant pigments (4-HPPD
inhibitor); terbuthylazine is a triazine which inhibits photosynthesis (photosystem II inhibitor).
Weed control can be reduced if strains of individual weed species develop that are less sensitive to a specific herbicide, or herbicide group.
FARMCO MAIZE, a formulated mixture of two active ingredients with two different modes of action, will reduce the likelihood of resistance development. There is no known cross resistance between mesotrione or terbuthylazine, or the groups of herbicides to which each belongs.
Furthermore at the present time, triketones (e.g. Mesotrione) are not approved in crops other than maize. There is no similar mode of action in herbicides for other crops and therefore crop rotation will also delay the onset of any resistance to this active ingredient. Where continuous maize is grown, the use of FARMCO MAIZE for more than two seasons should be avoided.
