Problems solved by technology

Chlorothalonil has no systemic conduction effect, but after spraying on the plant body, it can have good adhesion on the body surface and is not easily washed away by rain, so the drug effect period is longer

Embodiment 2

[0021] Formulation Example 2 : 60% benthiazil · chlorothalonil water dispersible granules.

[0022] The following substances are in mass percent: 12% benthiazil, 48% chlorothalonil, 4% sodium lignosulfonate, 3% sodium naphthalenesulfonate formaldehyde condensate, 2% sodium chloride, 1% soluble starch, poly Vinyl alcohol 3%, ammonium sulfate 5%, the balance is kaolin. The above formula was dry crushed according to the proportion, extruded granulated, dried and sieved to prepare 60% benthiazil·chlorothalonil water dispersible granules.

Embodiment 1

[0023] Bioassay Example 1 : Determination of combined effect of benthiazil and chlorothalonil mixture on cucumber downy mildew.

[0024] In order to further understand the combined effect of benthiazil and chlorothalonil on cucumber downy mildew, the inventors have carried out a large number of field formula screening tests on the mixture of benthiazil and chlorothalonil. Through field experiments, we It was found that the best control effect was achieved when benthiazil and chlorothalonil were mixed according to the ratio of ~. The mixed use of the two can significantly improve the control effect compared with the use of a single dosage form, and the control effect is also significantly higher than other types of compound ratios.

[0025] The field efficacy test scheme of the mixed compositions of benthiazil and chlorothalonil with different mass ratios for controlling cucumber downy mildew is as follows:

[0026] Benthiopyram and chlorothalonil were respectively made into...

Abstract

The invention relates to a benthiavalicarb isopropyl / chlorothalonil bactericidal composition which is composed of benthiavalicarb isopropyl and chlorothalonil in a mass ratio of 1:1-1:10. The bactericidal composition provided by the invention is suitable for controlling downy mildew of cucumber. The benthiavalicarb isopropyl / chlorothalonil compound has obvious synergistic action, has favorable control effect on downy mildew of cucumber, lowers the pesticide consumption to some extent, saves the cost, reduces the negative influence on the environment, is convenient to use, and has strong operability and high practical application value.

Description

technical field [0001] The bactericidal composition involved in the invention uses benthiazil and chlorothalonil as active ingredients and is used for preventing and treating cucumber downy mildew. Background technique [0002] Benthiazil, English name: benthiavalicarb-isopropyl, chemical name [[(6-fluorobenzothiazol-2-yl)-ethylcarbamoyl]-2-methylpropyl]carbamate isopropyl. The new fungicide, benthiazil, has strong preventive, therapeutic and permeation activities, and has good persistence and resistance to rain erosion. In field trials, benthiazil can still effectively control late blight of potato and tomato, downy mildew of grapes and other crops at a lower dosage. The mixture of benthiazil and other fungicides can also have a very good effect on these bacteria. [0003] Chlorothalonil, English common name: chlorothalonil, is a broad-spectrum, protective fungicide. The mechanism of action is that it can interact with glyceraldehyde triphosphate dehydrogenase in fungal ...
