Technical Field
The invention specifically relates to the technical field of pesticide compounding, and specifically relates to a bactericidal composition containing thiophanate methyl and thiasentong.
Background
Thiophanate methyl, which is a broad-spectrum systemic low-toxicity fungicide, has systemic, preventive and therapeutic effects. It was originally developed by Nippon Caoda corporation. Can effectively prevent and control diseases of various crops. The prevention and treatment of vegetable diseases can prevent and treat powdery mildew of cucumber, anthracnose, gray mold of eggplant, onion, celery, tomato, kidney bean and the like, anthracnose and sclerotinia, 1000-fold liquid of 50 percent wettable powder can be used for spraying for 1 time every 7 to 10 days and continuously spraying for 3 to 4 times at the initial stage of disease attack; can be used for preventing and treating lettuce gray mold and sclerotinia, and can be sprayed with 700 times of 50% wettable powder. The prevention and control of the flower diseases have certain prevention and control effects on dahlia flower rot, Chinese rose brown spot, Chinese flowering crabapple gray spot and kaffir lily leaf spot. In the initial stage of disease, 83-125 g of 50% wettable powder is used per mu, and is mixed with water for conventional spraying for 3-5 times.
Thiessen copper is thiazole organic copper bactericide, and is mainly used for preventing and treating rice bacterial leaf blight, bacterial leaf streak, cabbage soft rot and tomato bacterial wilt. Broad spectrum, low toxicity, safety, environmental protection, no public nuisance, special effect on bacterial diseases, high efficiency on fungal diseases, stability under acidic condition, and capability of being mixed with other pesticides.
Application of chemical agents is the most effective means of controlling plant diseases. However, continuous application of a single chemical fungicide in a high dose for a long period of time is likely to cause problems such as drug residue, environmental pollution, and development of drug-resistant fungi. The reasonable compounding or mixing of the chemical bactericide has the positive characteristics of expanding the bactericidal spectrum, improving the control effect, prolonging the application suitable period, reducing the dosage, reducing the phytotoxicity, reducing the residue, delaying the occurrence and the development of the drug resistance and the like of fungi, and the compounding of the bactericide is one of the most effective methods for solving the problems. The price of developing new products of bactericides is continuously rising, and compared with the price of developing and researching high-efficiency, low-toxicity and low-residue compounding and mixing, the bactericide has the advantages of low investment, short development period, attention paid to at home and abroad, and development strength are increased in many cases. On the basis of indoor screening and field tests, the thiophanate methyl and the thiessen copper are screened out for compounding, and the synergistic effect is obvious. And no report is made on the compounded sterilizing composition of thiophanate methyl and thiasentong and the application thereof at present.
