Embodiment 1

[0071] Weigh 25% fluopyram, 10% fenhexamid, 5% fatty alcohol polyoxyethylene ether phosphate, 6% alkylnaphthalene sulfonate formaldehyde condensate, 4% alkylsulfonate sodium, talcum powder up to 100% by weight. The above raw materials are mixed, pulverized by ultra-fine airflow, and mixed to prepare 35% fluopyram·fenhexamid wettable powder.

Embodiment 2

[0073] Weigh 20% fluopyram, 25% fenhexamid, 6% calcium lignosulfonate, 3% alkylnaphthalene sulfonate formaldehyde condensate, 2.5% sodium lauryl sulfate, add enough attapulgite to 100% by weight. The above raw materials are mixed, pulverized by ultra-fine airflow, and mixed to prepare 45% fluopyram·fenhexamid wettable powder.

Embodiment 3

[0075] Weigh 15% fluopyram, 10% fenhexamid, 5% polycarboxylate T36, 3% sodium alkylnaphthalene sulfonate, 3% pull open powder BX (sodium dibutylnaphthalene sulfonate), 2 % sodium lauryl sulfate, 2% polyethylene glycol, light calcium added to 100% parts by weight. The above-mentioned raw materials are prepared through the conventional method for preparing water-dispersible granules, ie, mixing, ultrafine airflow pulverization, mixing, and granulation to prepare 25% fluopyram·fenhexamid water-dispersible granules.

Abstract

The invention discloses a sterilization composition containing fluopyram and fenhexamid. Effective active ingredients consist of a first active ingredient fluopyram and a second active ingredient fenhexamid; a weight ratio of the first active ingredient to the second active ingredient is (1:80) to (60:1), preferably is (1:60) to (40:1) and the most preferably is (1:30) to (20:1). The composition can be prepared into preparations of wettable powder, water dispersible granules, a suspension agent, suspoemulsion, emulsion in water, microemulsion, aqueous capsule suspension, an aqueous capsule suspension-suspension agent, a dispersible oil suspension agent and dry flowable, which are allowed agriculturally. The sterilization composition is reasonable in component and good in sterilization effect; the activity and the sterilization effect of the composition are not simple overlapping of the activity of each component; compared with an existing single preparation, the sterilization composition not only has the obvious sterilization effect, but also has an obvious synergistic effect and has high safety for crops. The sterilization composition has obvious prevention and treatment effects on botrytis cinerea, brown rot, powdery mildew, early blight and venturia inaequalis of the crops.

Description

technical field [0001] The invention relates to a bactericidal composition, which is composed of a first active ingredient fluopyram, a second active ingredient fenhexamid and an auxiliary agent, and belongs to the technical field of compound pesticides. Background technique [0002] Fluopyram, the English name is fluopyram, the chemical name is N-{2-[3-chloro-5-(trifluoromethyl)-2-pyridyl]ethyl]-α,α,α-trifluoro- O-toluamide is a new type of benzamide fungicide, which acts on the complex II of the mitochondrial respiratory electron transport chain [that is, succinate dehydrogenase (succinate dehydrogenase, SDH) or succinate coenzyme Q reductase (succinate- coenzymeQreductase, SQR)], which inhibits mitochondrial respiration by hindering the electron transfer of succinate dehydrogenase in the respiratory chain. It is mainly used to control diseases caused by cyst fungi on broad-leaved crops. It has a good control effect on various diseases such as powdery mildew and target s...
