Description

Composition containing carbosulfan, clothianidin and fludioxonil and application thereof Technical Field The invention relates to the field of pesticides, in particular to an application of a composition containing carbosulfan, clothianidin and fludioxonil in preventing and controlling plant diseases and insect pests. Background Carbosulfan (Carbosulfan), trade names of winter, an Miante, and Ding Liuwei, belongs to carbamate insecticidal acaricide, and has a chemical formula of C 20H32N2O3 S and CAS number 55285-14-8, and the structural formula is shown in formula 1: Formula 1. Carbosulfan is colorless or pale yellow oily liquid, has a density of 1.1+ -0.1 g/cm3, and vapor pressure of 4.1X10 4 Pa (25deg.C), is insoluble in water, and is easily dissolved in organic solvent. The oral LD 50 male rat is 224 mg/kg, the female rat is 187 mg/kg, and the pesticide belongs to moderate toxic pesticide. The pesticide has the advantages of strong permeability, low residue and rapid action by inhibiting the activities of acetylcholinesterase and carboxylesterase, has the effects of contact killing and stomach poisoning on pests such as aphids, borers, leafhoppers and the like, has low toxicity to natural enemies and beneficial organisms, and is a safe substitute for the virulent pesticide carbofuran. The pesticide composition is mainly used for controlling pests of crops such as citrus, cotton, rice and the like, and can effectively control various pests such as rust ticks, diving She E, thrips, sugarcane borers and the like. Clothianidin is a general name of a compound (E) -1- (2-chloro-1, 3-thiazol-5-ylmethyl) -3-methyl-2-nitroguanidine, 1- (2-chloro-5-thiazolylmethyl) -3-methyl-2-nitroguanidine, an English general name is clothianidin, a molecular formula is C 6H8ClN5O2 S, a relative molecular weight is 249.7, a CAS number is 210880-92-5, and a structural formula is shown in a formula 2: Formula 2. Clothianidin is one of neonicotinoids, and is a high-efficiency, safe and high-selectivity novel pesticide with the functions similar to that of a nicotinic acetylcholine receptor and with contact killing, stomach toxicity and systemic activity. The pesticide is mainly used for preventing and controlling hemiptera, coleoptera, diptera and some lepidoptera pests on rice, vegetables, fruit trees and other crops, has the advantages of high efficiency, broad spectrum, small dosage, low toxicity, long efficacy duration, no phytotoxicity to crops, safe use, no interactive resistance with conventional pesticides and the like, has excellent systemic and osmotic effects, and is a further variety for replacing high-toxic organophosphorus pesticides. The novel and special structure has better performance than the traditional nicotine pesticide, and can become a large-scale pesticide variety worldwide. Fludioxonil is a non-systemic fungicide that can be absorbed by plant tissues to inhibit mitogen-activated protein kinase activity during osmotic signaling. Fludioxonil is a common name of the compound 4- (2, 2-difluoro-1, 3-benzodioxol-4-yl) pyrrole-3-carbonitrile, the English common name is fluxiaoil, the molecular formula is C 12H6F2N2O2, the relative molecular weight is 248.2, the CAS number is 131341-86-1, and the structural formula is shown in formula 3: Formula 3. Those skilled in the art will recognize that the effects of compounding pesticide ingredients are unpredictable and generally manifest as antagonistic, additive and synergistic effects. The prior art does not report that carbosulfan, clothianidin and fludioxonil are mixed, and the inventor discovers that the carbosulfan, clothianidin and fludioxonil have better synergistic effect after being mixed. In view of this, the present application has been completed. Disclosure of Invention The invention provides a specific synergistic ternary pesticide composition which consists of carbosulfan, clothianidin and fludioxonil as effective components. Preferably, the mass ratio of carbosulfan, clothianidin and fludioxonil is 24-8:8-24:0.5-4. In a second aspect the present invention provides a composition comprising a pesticidal composition according to the present invention and a suitable pesticidal adjuvant. The invention also provides application of the composition and the preparation in preventing and controlling plant diseases and insect pests.
