Embodiment 1

[0033] Embodiment 1: four kinds of pesticides are as follows to the effect contrast of greenhouse potted plant of downy mildew:

[0034]

[0035] The drug efficacy experiment shows that the control effect of the composition prepared by the invention is obviously better than that of a single dose to downy mildew.

[0036]

Embodiment 2

[0037] Embodiment 2: four kinds of pesticides are as follows to the comparison situation of the effect of greenhouse potting to cucumber gray mold:

[0038]

[0039] The efficacy experiment shows that the control effect of the prepared composition of the invention on cucumber gray mold is obviously better than that of a single agent.

[0040]

Embodiment 3

[0041] Embodiment 3: four kinds of pesticides are to the effect of greenhouse potting of downy mildew bacterial strain

[0042]

[0043] The efficacy experiment shows that the control effect of the prepared composition of the invention on downy mildew bacterial strains is better than that of a single agent, especially much better than that of a bacteriostasis agent.

Abstract

The invention provides a composite pesticide of cyclohexyl flusulfamide and chlorothalonil. The mole ratio of cyclohexyl flusulfamide to chlorothalonil is (1: 2)-(2: 1) and a coordination bond is arranged between the two molecular structures to strengthen the pesticide effect. When the composite pesticide is in emulsion type, the content of a solvent is 50-65wt% and an emulsifier is one or several of a pesticide emulsifier 0203, a pesticide emulsifier 0201, GFC, OP-10, tween-60 and a pesticide emulsifier OX-2568, which are capable of well emulsifying cyclohexyl flusulfamide and chlorothalonil in a water solution; when the composite pesticide is in wettable powder type, the dosage of a disperser is 5-15wt% and the disperser is one or several of sodium lignin sulfonate, sodium 1-naphthalenesulfonate, polyethylene glycol and alkylphenol polyoxyethylene phosphate, which are capable of forming a favorable dispersing system with the water solution of cyclohexyl flusulfamide and chlorothalonil. The composite pesticide has the purpose of favorably preventing and treating the downy mildew and the gray mold of the plants. According to the composite pesticide, the concentration of active ingredients is relatively low, the dosage is relatively less, the spraying is carried out once to twice and 25-50% of synergistic function is brought to the prevention and treatment of the downy mildew and the gray mold.

Description

technical field [0001] The invention relates to a new pesticide product whose bactericidal component is cyclohexasulfame or chlorothalonil and its use and usage. Background technique [0002] The description of the patent application number ZL201210346240.8 introduces a new type of fungicide chesulfamide, its chemical structure is N-(2-trifluoromethyl-4-chlorophenyl)-2- Oxocyclohexyl sulfonamide can be used to control various crop diseases such as tomato gray mold, rape sclerotinia, cucumber brown spot and so on. [0003] In 2012, on pages 287-288 of the 51st issue of "Pesticides", the research on the microscopic morphology of cyclazone and the cell membrane permeability test showed that cyclazone acts on the mycelial cell membrane, making its DNA and polysaccharides Cyclosulfame can induce systemic disease resistance in plants, and still exhibits good activity against some resistant strains, indicating that its mechanism of action is different from that of existing commerc...
