preparation preparation example

[0025] The active components of the preparation are A and B; component A is selected from fluthiapiprofen, component B is selected from enoxostrobin, enoxastrobin, pyraclostrobin or syringethrin, and components A and The weight ratio between the two components of component B is any ratio between 1:1000-200:1, and then configure different dosage forms in the following manner, specifically as follows:

[0026] Suspending agent (SC)

[0027] In the agitated ball mill, add 20% of the pulverized active ingredients of the composition, 5% of sodium naphthalenesulfonate formaldehyde condensate, 0.08% xanthan gum, 0.1% white carbon black, 4.0% agricultural milk 0201B, 4% ethyl alcohol Glycol, a little antifoam, and finally water to make up to 100%, makes a finely divided active ingredient suspension. Dilute with water to obtain a suspension for foliage spray or soil irrigation.

Embodiment 1

[0046] Embodiment 1 control cucumber downy mildew test (living body)

[0047]Potted cucumber seedlings were sprayed with components A, B and the composition's aqueous solution (concentration is as follows), after 24 hours, the cucumber downy mildew spore suspension was inoculated on the cucumber leaves, and then placed at a temperature of 24 ± Cultivate in a climate chamber at 1°C and a relative humidity of 90±5%, then place in a greenhouse for normal cultivation, and measure the degree of pathogen infection on the leaves after 7 days. See Table 1 and Table 2 for the activity data of each individual active component and the composition of the present invention on cucumber downy mildew.

[0048] The results show that the observed potency values ​​of the composition are all greater than the calculated potency values, and the composition exhibits a synergistic effect within the test proportion range.

Abstract

The invention belongs to the field of agricultural fungicides, and particularly relates to an oxathiapiprolin-containing composition and applications thereof, wherein the composition comprises a component A and a component B, the component A is selected from oxathiapiprolin, the component B is selected from a methoxy acrylate fungicide, and a weight ratio of the component A to the component B is 1:1000-200:1. According to the present invention, the pesticide composition has a good synergistic effect, and has obviously-improved prevention and control effects on crop diseases; the pesticides with different action mechanisms are combined, such that the sterilization spectrum of the agent can be expanded, the generation of the drug resistance of pathogenic bacteria can be delayed, and the service life of the agent can be prolonged; and the two pesticides are combined according to the suitable ratio of the present invention in the agricultural production so as to achieve the effects of labor saving and time saving.

Description

technical field [0001] The invention belongs to the field of agricultural fungicides, and in particular relates to a pesticide composition containing fluthiapiprofen and its application. Background technique [0002] Ethoxystrobin, enoxastrobin, pyraclostrobin or syringethrin are commonly used fungicides of methoxyacrylates, and are widely used in crop diseases. However, in the process of agricultural production, due to the repeated use of these agents for many years, coupled with their single action site, the problem of resistance of plant pathogens to the agents is becoming more and more serious. On the other hand, consumers' demand for reducing the amount of pesticide residues in agricultural products and the social demand for alleviating environmental problems caused by the use of chemical pesticides are also increasing. It is desired to use a composition and a use method that are highly effective and have good control effects on plant disease fungi that have developed ...
