Mesotrione is a broad spectrum selective herbicide that can inhibit hydroxyphenylpyruvate dioxidase (HPPD) before and after shoot, which can effectively control the main broad-leaved grass and some grass weeds.Mesotrione has good control effect on annual broad-leaved weeds in maize field and some grasses such as abutilon, amaranth, quinoa, polygonum polygonum, barnyard grass and matang.However, the control effect of iron amaranth and some grass weeds is poor.
Atrazine is a selective pre - and post - seedling herbicide.It is mainly absorbed by root, but little by stem and leaf, which is quickly transmitted to plant meristem and leaf, interfering with photosynthesis and killing weeds.In corn and other resistant crops, corn ketenase is decomposed into non-toxic substances, so it is safe for crops.
Applicable crops:
Mesotrione 10%+Atrazine 40% SC is highly water-soluble, has greater mobility in soil than simazine, and is easily washed by rain to deeper depths, resulting in an inhibitory effect on some deep-rooted weeds, which can be decomposed by microorganisms in the soil. The residual effect period can be as long as half a year depending on the dosage of the drug, soil texture and other factors.Suitable for the control of annual and biennial broad-leaved weeds and monocotyledon weeds in corn, sorghum, woodland, grassland, sugarcane, etc.Corn used once a season is safe for corn at the recommended dose.
