Embodiment 1
[0010] Example 1: 55% polyoxin · benthiazil water dispersible granules
[0011] 5g polyoxin, 50g benthiazil, 4g sodium lauryl sulfate, 2g sodium lignosulfonate, 4g ammonium sulfate, 2g gum arabic, kaolin supplemented to 100g, made 55% polyoxin·benzene Thifluzamide water dispersible granules.
Embodiment 2
[0012] Example 2: 55% polyoxin · benthiazil water dispersible granules
[0013] 50g polyoxin, 5g benthiazil, 4g sodium lauryl sulfate, 2g sodium lignosulfonate, 4g ammonium sulfate, 2g gum arabic, and kaolin were added to 100g to prepare 55% polyoxin·benzene Thifluzamide water dispersible granules.
[0014] According to the formula of Examples 1 and 2, the active ingredients, additives, and fillers are mixed, and after stirring evenly, the mother powder is obtained by crushing, and the mother powder and the binder are mixed evenly, and then granulated, dried, and sieved, that is It can be made into water dispersible granules of polyamycin·benthiopyram.
Embodiment 3
[0015] Example 3 : 50% polyoxin · benthiazil wettable powder
[0016] 25g polyoxin, 25g benthiazil, 4g sodium lauryl sulfate, 4g sodium lignosulfonate, and kaolin make up 100g. Prepared 50% polyoxin · benthiazil wettable powder.

Abstract
The invention discloses a bactericide composition containing polyoxins and benthiavalicarb isopropyl and belongs to the technical field of pesticide. Based on active components, the weight ratio of the polyoxins to the benthiavalicarb isopropyl is 1:10-10:1. The bactericide composition further comprises an additive and filler, wherein the polyoxins and the benthiavalicarb isopropyl occupy 5%-60% of the total weight of the bactericide, the additive occupies 5%-30% of the total weight of the bactericide, and the rest is the filler. Through actual tests, the bactericide has obvious control efficiency on wheat scab. Compared with a conventional wheat scab bactericide, the composite bactericide has the following advantages that compared with a single bactericide, the bactericide composition has the obvious synergistic effect on the wheat scab and can obviously improve the control efficiency; can replace parts of intermediately and highly toxic bactericides, reduce dosage, lower environment pollution and residuals in agricultural products and delay pesticide resistance of the wheat scab to the single bactericide, is long in lasting period, and can reduce cost compared with a single medicament.
Description
technical field [0001] The invention belongs to the technical field of pesticides, and relates to a fungicide for preventing and treating wheat scab. Background technique [0002] Wheat head blight is a worldwide epidemic disease, which can lead to yield reduction, and mycotoxins remain in wheat, posing a huge threat to wheat production. The disease occurs seriously in the winter wheat region in the middle and lower reaches of the Yangtze River and the spring wheat region in Northeast China, where there is much rain at the heading stage and the climate is humid. It also occurs frequently in other wheat regions, causing great losses. Since the main varieties planted in large-scale production are susceptible or moderately resistant varieties, chemical control is still an important means to control head blight. In production, the main agents used to prevent and control the disease are benzimidazole and triazole fungicides, and drug resistance has emerged after years of use. ...
