The active ingredient is an inorganic pesticide containing arsenic compounds. Highly toxic to higher animals. Arsenic acid anhydride and calcium arsenate are highly toxic to aquatic organisms such as fish, and lead arsenate is less toxic to fish and other aquatic organisms. Arsenic preparations are mainly protoplasmic poisons and have stomach poisoning effects.
Apply to powder, wettable powder, paste and poison baits. The antimony anhydride and calcium arsenate are formulated as baits for controlling underground pests, aphids, and rodents. Lead arsenate and calcium arsenate are processed into powders and wettable powders to control chewing mouthpart pests that damage rice, cotton, fruit trees and vegetables. For example, lead arsenate can be used to control rice borers, rice borers, cotton red bells Insects, leaf curlers, diamond drills, small bridge insects, date tapeworms, pear scales, persimmon stars, wood --- ulmes, apple borers, codling moths, pear borerworms, gypsy moths, cabbage worms, etc. Calcium arsenate can be used to control rice negative slime, tobacco stemworm, armyworm, all kinds of leaf armor, cotton bollworm, cotton boll weevil, corn borer, date worm, apple borer moth, twenty-eight star ladybug. Due to phytotoxicity, arsenite cannot be directly applied to crops. Lead arsenate cannot be used in peaches, plums, apricots, persimmons, soybeans, Beans and other crops. Molybdenum arsenate cannot be used in pears, persimmons, peaches, apricots, soybeans. And other crops. To prevent phytotoxicity, special care must be taken when applying arsenic preparations. When applying pesticides, attention must be paid to labor protection. After application, people and animals must be prevented from entering the application area to avoid poisoning.
