Technical Field

The invention belongs to the field of agricultural pesticides, and particularly relates to an insecticidal mite and pathogenic microorganism composition and application thereof.

Background

Chinese invention patent CN201611199611.9 and PCT application WOCN16111411 disclose malononitrile oxime ether compounds, which have good control effects on plant mites, fungi and bacteria. The malononitrile oxime ether compound has good control effect on various plant diseases caused by oomycetes, basidiomycetes, ascomycetes, deuteromycetes and other plant pathogenic bacteria, including cucumber downy mildew, cucumber gray mold, cucumber anthracnose, cucumber powdery mildew, tomato early blight, tomato late blight, pepper epidemic disease, grape downy mildew, grape white rot, apple ring spot, apple alternaria leaf spot, rice sheath blight, rice blast, wheat rust, wheat leaf spot, wheat powdery mildew, rape sclerotinia rot, corn small spot and the like; meanwhile, the composition has good control effects on various plant diseases caused by plant pathogenic bacteria such as pseudomonas, erwinia, xanthomonas, acidophilus and the like, including tomato bacterial wilt, tobacco bacterial wilt, citrus canker, kiwi canker, Chinese cabbage soft rot, cucumber bacterial angular leaf spot and the like.

Practical agricultural experience and a great deal of scientific research data show that pest mites and bacterial diseases often occur in the same period, so that the control period of the pest mites and the control period of the bacterial diseases are basically consistent. However, the mutual influence between the acaricidal agent and the bactericide is uncertain, and sometimes the bactericide can stimulate mites to lay eggs, so that the effect of the acaricidal agent is seriously influenced, and the acaricidal agent is ineffective. Therefore, users usually try to avoid the simultaneous use of two types of pesticides.

However, in rainy seasons in south China, rainfall has great influence on the pesticide application process and the pesticide effect, and the non-rainfall time suitable for pesticide application is often less than one day or even only a few hours within dozens of days, so that the bactericide and the acaricide are inevitably used simultaneously. Under such a complicated environment, the difficulty of effectively controlling the plant diseases and insect pests is very high.

Detailed Description

The synergistic effect of the insecticidal acaricidal, fungal, bacterial compositions of the present invention on harmful acarids and bacterial diseases is illustrated by the following examples, but the present invention is by no means limited thereto.

The active compounds, alone or in combination, are prepared as acetone or DMSO stock solutions containing 0.25% by weight of active compound. 1% by weight of emulsifierEL (a wetting agent based on ethoxylated alkylphenol having emulsifying and dispersing effects) is added to the stock solution, andthe active compound or mixture was diluted with water to the desired concentration in the examples below.

The expected potency of the active compound mixtures was determined using the Colby formula [ S.R.Colby.calcium synergy and antibiotic Responses of pharmaceutical compositions.Weeds, 1967,15(1):20-22] and compared with the observed potency.

Colby formula: e ═ x + y-xy/100

E: the expected efficacy when using mixtures of active compounds a and B at concentrations a and B, respectively, is expressed as% of the untreated control.

x efficacy when using active compound a at a concentration a, expressed as% of untreated control;

y efficacy when using active compound B at a concentration of B, expressed as% of the untreated control.

If the actual observed efficacy (O) is greater than the expected efficacy (E), the effect of the combination is a synergistic effect, which corresponds mathematically to a positive difference in (O-E). If the actual observed efficacy (O) is equal to the expected efficacy (E), the effect of the combination is a purely additive effect, showing no synergy, mathematically the difference corresponding to (O-E) is zero. If the actual observed potency (O) is less than the expected potency (E), then the effect of the combination is an antagonistic effect, mathematically the difference corresponding to (O-E) is negative.
