Cyazofamid is a new type of low toxic bactericide. It has good protective activity and a certain activity of internal absorption. It has a long holding period and rain erosion resistance. It is safe and convenient to use. The drug is a mitochondrial respiratory inhibitor, which is different from the methoxy acrylate (QO inhibitor in cytochrome BCL) by inhibiting the Qi of cytochrome BCL in the metabolic process of the pathogen. It has effect on all growth stages of oophthora, and is active against metalaxyl resistant or susceptible bacteria.
Control of all stages of major Lepidoptera and Coleoptera pests and some hemiptera and Diptera on cotton, soya beans, maize, vines, fruit, vegetables, and many other crops. Seed treatment rates are 2500-10 000 g/tonne. Also used as a molluscicide for control of slugs in cereals and oilseed rape.
Thiram is the simplest thiuram disulfide and the oxidized dimer of dimethyldithiocarbamate. It is used as a fungicide, ectoparasiticide to prevent fungal diseases in seed and crops and similarly as a animal repellent to protect fruit trees and ornamentals from damage by rabbits, rodents and deer. It is effective against Stem gall of coriander, damping off, smut of millet, neck rot of onion, etc. Thiram has been used in the treatment of human scabies, as a sun screen and as a bactericide applied directly to the skin or incorporated into soap.
Carbosulfan is a low toxic derivative from Carbofuran. It can kill pests and mites with broad spectrum, strong and quick effect, stomach and contact action. It is safe to crops and effective to both pests and larva by good fatsolubility and systemic properties, low residue and long-term effect. It is used to protect citrus, vegetable, maize, cotton, rice, sugarcane, etc. Especially good result can be got for killing aphids.
