Answer: Nicosulfuron is a herbicide commonly used in corn fields and is currently used in a large area in production. The use of nicosulfuron in past years has caused phytotoxicity to the corn, which may be caused by corn varieties being sensitive to the drug or using improper methods. Different maize varieties have different susceptibility to nicosulfuron. Most sweet corn varieties are sensitive to the drug, and some common corn hybrids are also sensitive. It is generally safer to use on dents and semi-dental corn varieties and should not be used on popcorn or sweet corn. For nicosulfuron moderately sensitive varieties, nicosulfuron is used under high-temperature, low-temperature, drought, fertilizer damage, lack of mineral elements and other adverse conditions, or a large amount of drug may also cause phytotoxicity. Maize 3-5 leaf stage has the strongest metabolic ability to nicosulfuron and gradually decreases after 6 leaf stage. The application of nicosulfuron before and after the two-leaf stage of maize was susceptible to phytotoxicity. Nicosulfuron was prone to phytotoxicity when mixed with 2,4-D, 2A, 4-Chloro, and Picraxone. The use of organophosphorus pesticides within 7 days before and after application with organophosphorus pesticides may also cause phytotoxicity. Pay attention to these problems and scientifically apply nicosulfuron to avoid the occurrence of phytotoxicity. Compared with nicosulfuron and other drugs, mesotrione, oxacillone and other drugs have good safety to corn, and they are relatively safe to use on sweet waxy corn. Among them, BASF Europe (telephone) defends 30% oxacillone suspension agent (telephone contact phone in Jiangsu Province) and will be listed in China this year. The drug is registered for the control of annual weeds in corn fields and has a broad spectrum of grass weed control. It can control grassy weeds and broad-leaved weeds in the warm season of the year, and in particular, can effectively prevent mesotrione and horses that are not effective against mesotrione. Tang, goosegrass, can be used for all types of corn (field corn, feed corn, and breeding seed corn), and it exhibits good selectivity for popcorn and sweet corn, but it should be tested on inbred corn. Under extreme weather conditions, or when maize is subjected to post-emergence stress under stress, occasional transient bleaching reactions occur occasionally, but normal growth can usually resume very quickly.
