Embodiment 1

[0053] Indoor Toxicity Determination of Fludioxonil and Thiofuramide against Peanut Siberia

[0054] Pathogen tested: Sclerotium rolfsii Sacc, provided by Plant Pathology Department, Plant Protection College, Anhui Agricultural University.

[0055] Test agents: 97% of fludioxonil and 97% of thifuramide were provided by the Research Center of Hailier Pharmaceutical Group Co., Ltd.

[0056] Medicament preparation: 97% fludioxonil and 97% thifluzamide original drugs are first dissolved in acetone, and then diluted with 0.1% Tween 80 aqueous solution. Prepare single-dose mother liquors respectively, and design 5 groups of proportions according to the mixing purpose and drug activity, and prepare 5 series of mass concentrations for each single dose and each group of proportioned mixtures according to the method of equal ratio.

[0057] Under aseptic operation conditions, according to the test treatment, add 45ml of pre-thawed sterilized medium into a sterile conical flask, draw 5m...

preparation example 1

[0105] 21% Fludioxonil · Thiofuramide · Clothianidin Suspension Seed Coating

[0106] Disperse 3 g of alkylnaphthalene sulfonate formaldehyde condensate, 1 g of EO-PO block copolymer, 2 g of sodium lauryl sulfate and 0.5 g of organic silicon defoamer in 50 g of water, and disperse 0.5 g of fludioxonil technical substance in it , 0.5 g of the original drug of thiafluxamide and 20 g of the original drug of clothianidin were wet-milled with a sand mill to D90 (90% particle size)<10 μm using glass beads to obtain a crushed slurry. Add 0.2g of xanthan gum, 1.0g of magnesium aluminum silicate, 5g of ethylene glycol, and 0.5g of sodium benzoate to the pulverized slurry and mix evenly, make up to 100g with deionized water, and shear at a high speed to obtain an active ingredient mass content of 21wt % of the suspended seed coating agent.

Abstract

The invention relates to application of a farm chemical composition containing fludioxonil and thifluzamide in prevention and treatment of peanut diseases or insect pests. The effective components comprise fludioxonil and thifluzamide, and the mass ratio of the fludioxonil to the thifluzamide is 6:1 to 1:10. According to the technical scheme, the composition has an obvious synergistic effect on prevention and treatment of peanut diseases or insect pests, especially southern blight, can effectively overcome the defects of use of a single agent, and has a broad-spectrum bactericidal effect; thelasting period of the pesticide can be prolonged, the pesticide use frequency is reduced, the use amount and the use cost of chemical pesticides are effectively reduced, and the composition is environmentally friendly; and generation and development of resistance can be effectively delayed.

Description

technical field [0001] The invention relates to the technical field of pesticides, in particular to the use of a pesticide composition comprising fludioxonil and thiafluxamide in preventing and controlling peanut diseases or pests. Background technique [0002] Peanut is one of the most important oil crops in the world, its planting area is second only to rapeseed, and occupies a pivotal position in the world's oil production. Peanut canker sore is a common soil-borne fungal disease caused by Sclerotium rolfsii Sacc., which has a wide range of hosts and can infect more than 500 kinds of plants, including wheat, soybean, peanut , sesame, tomato, sunflower and some other important crops. In the past 10 years, the number of occurrences of peanut blight in major peanut production areas such as Shandong, Henan, Guangdong, Liaoning, and Jiangxi has increased year by year, and it has become an important factor restricting peanut production and quality. [0003] Peanut canker sore...
