6 GENERAL DESCRIPTION:

Metsulfuron is an extremely potent herbicide on some annual and perennial broad-leaved species.
It is a selective, translocated herbicide that is mainly absorbed through leaves though root absorption can occur. Its main uses are for broad-leaved weed (especially sorrel) control in cereals, as a tank mix with glyphosate for pre-plant weed control and for the control of perennial weeds such as bracken and blackberry. It is of low toxicity to mammals, birds and fish. Metsulfuron acts on the ALS enzyme in plants which is not present in animals and this is the main reason for its low toxicity. It presents little hazard in the environment because of its low rates of use, low toxicity and quick degradation in field situations.

7 APPLICATION METHODS AND TIPS:

Metsulfuron is usually applied in water as a broadcast application through hydraulic nozzles or as a directed spray using hand held equipment. It can be applied in ultra low volumes of carrier.
It is commonly mixed with other herbicides.
Surfactants often increase weed control but should not be used when metsulfuron is tank mixed with other herbicides for selective weed control in crops.
Under stressed conditions weeds become more tolerant and crops less tolerant to metsulfuron. For each 10 degree drop in temperature the crops ability to break down metsulfuron drops by a factor of 2 to 5, thus under cold conditions crop damage is more likely.

11 COMPATIBILITY:

Non-ionic surfactants and crop oils increase absorption.
Metsulfuron is generally antagonistic with the grass herbicides. It is synergistic with chlorsulfuron and possibly with the hormonal herbicides and glyphosate.
Trace elements: It is not compatible with most trace elements and ammonium sulphate.
See HerbiGuide Compatibilities button.

12 EQUIPMENT:

13 SPRAYER DECONTAMINATION:

Clean up:
Remove nozzles and filters and clean separately. Triple rinse with soapy water (eg 500 mL or g of Drive, Dynamo, Omo or Surf per 100 L water) or water plus 0.25% wetting agent and run through boom. This procedure is sufficient for spraying in other cereals or non selective applications.
Decontamination:
Remove the nozzles and screens and clean separately and allow to soak in a mixture of 500 mL chlorine bleach per 10 L water for at least 30 minutes.
Rinse sprayer with soapy water (eg 500 mL or g of Drive, Dynamo, Omo or Surf per 100 L water) or water plus 0.25% wetting agent and run through boom. Drain tank and flush with clean water for a minimum of 10 minutes to remove all traces of liquid fertilisers or adjuvants containing ammonia, such as ammonium sulphate or ammonium nitrate, before adding chlorine bleach, because bleach and ammonia will react to release a toxic gas.
Fill tank with clean water and add 300 mL household chlorine (4%) bleach per 100 L water, flush through hoses and boom then stand for 15 minutes with agitation engaged, repeat. Rinse tank, hoses and boom thoroughly with clean water to remove traces of bleach.
Rinse screens and nozzles and replace.

14 HERBICIDE RESISTANCE:

Plant populations tolerant to metsulfuron are expected to occur naturally after repeated applications of herbicides from the sulfonylurea group.
