Mesotrione is a broad-spectrum selective herbicide, which can inhibit hydroxyphenylpyruvate dioxygenase (HPPD) before and after germination, and can effectively control main broad-leaved weeds and some gramineous weeds.
As a systemic and broad-spectrum herbicide in corn field, mesotrione has contact killing and systemic effects. Sensitive weeds, when exposed to pesticides, conduct in xylem and phloem of plants, produce albinism symptoms, and then slowly die.
Mesotrione is mainly used to effectively control annual broad-leaved weeds and some gramineous weeds in corn fields, such as abutilon, Xanthium sibiricum, Amaranthus spinosus, Chenopodium, Polygonum cuspidatum, Kochia scoparia, mustard, barnyard grass, Stellaria, Solanum nigrum, crabgrass and other weeds.
It is not only safe for corn, but also safe for the environment and subsequent crops. It is especially effective for sulfonylurea herbicides, and it is an important variety to replace triazine herbicides such as atrazine, which has a long use time and a long residue period.
