Amitrol 240 Liquid Herbicide is most effective when sprayed on foliage of actively growing plants. Good coverage is essential for complete control. For good control of annual weeds spray early, usually before weeds are 10 cm in height. 
Apply in at least 50 litres of water per hectare unless otherwise stated. Good coverage of the weed is essential for good control, ensure adequate water is used to obtain good coverage. 
Apply Amitrol 240 Liquid Herbicide in the early morning or evening when the humidity is higher, for the best results. Avoid application when the daytime temperature exceeds 25 C and when air conditions are very dry. 
Avoid using rates higher than 20 litres/ hectare preplant in crop applications on very light soil with low organic matter. Crop damage may occur, particularly on sandy knolls. 
Amitrol 240 Liquid Herbicide prevents plant chlorophyll development. Weeds usually turn white and die slowly, taking between 2-6 weeks for complete control. 
Amitrol 240 Liquid Herbicide is inactivated in most soil and remains only in the root system of plant being controlled, thus it continues to affect shoots from the root until the entire plant is dead. 
Amitrol 240 Liquid Herbicide is a non-selective herbicide at rates needed to control most perennial weeds. If used under desirable plants or trees, avoid contact with foliage, green stems or fruit since severe injury or destruction may result. 
Do not apply more than twice per year. 


Field sprayer application: DO NOT apply during periods of dead calm. Avoid application of this product when winds are gusty. DO NOT apply with spray droplets smaller than the American Society of Agricultural Engineers (ASAE) medium classification. Boom height must be 60 cm or less above the crop or ground. 
DO NOT apply by air.


For resistance management, Amitrol 240 Liquid Herbicide is a Group 11 herbicide. Any weed population may contain or develop plants naturally resistant to Amitrol 240 Liquid Herbicide and other Group 11 herbicides. The resistant biotypes may dominate the weed population if these herbicides are used repeatedly in the same field. Other resistance mechanisms that are not linked to site of action, but specific for individual chemicals, such as enhanced metabolism, may also exist. Appropriate resistance-management strategies should be followed.
To delay herbicide resistance:
Where possible, rotate the use of Amitrol 240 Liquid Herbicide or other Group 11 herbicides with different herbicide groups that control the same weeds in a field.
Use tank mixtures with herbicides from a different group when such use is permitted.
Herbicide use should be based on an IPM program that includes scouting, historical information related to herbicide use and crop rotation, and considers tillage (or other mechanical), cultural, biological and other chemical control practices.
Monitor treated weed populations for resistance development.
Prevent movement of resistant weed seeds to other fields by cleaning harvesting and tillage equipment and planting clean seed.
Contact your local extension specialist or certified crop advisors for any additional pesticide resistance-management and/or integrated weed-management recommendations for specific crops and weed biotypes.
