  1. Pyrithiobac-sodium (Pyrithiobac-sodium) is also known as Pyrithiobac-sodium. Low toxicity, it is an acetolactate synthase inhibitor. It can control annual and perennial grass weeds and most broadleaf weeds in cotton fields. Chemicalbook has a good control effect on difficult weeds such as morning glory, cocklebur, abutilon, arabic sorghum, etc. Used in cotton field, it can be used before and after seedling, soil treatment and stem and leaf treatment can be used.
  2. Use 30 to 70 grams of 10% wettable powder or 8 to 25 grams of 28% suspending agent per mu and spray on the water. It is a new generation of broad-spectrum herbicide developed by Japan Combinatorial Chemical Company and listed in 1994.

  1. Among the numerous chemical herbicides, pyrimidinoxy (sulfur) benzoate herbicides are an excellent, new type of herbicides for rice and cotton, with high efficiency, low toxicity, and low residue characteristics. Among them, pyrimazine sulfide is a special cotton herbicide, which is safe for cotton. my country is a major producer of cotton Chemicalbook, and the development of cotton herbicides is imminent.
  2. At present, the herbicides used in cotton fields in China have unsatisfactory control effects. Some weeds are also resistant to pesticides. Imported herbicides are expensive. Therefore, our development of pyrimethalin is of great significance to my country’s cotton production.
