Problems solved by technology

[0002] In agricultural production, the quality of seeds directly affects the production of crops, and the seeds from germination to seedling stage are easy to be carried by seeds or infected by pathogenic bacteria in the soil, and gnawed by insects, resulting in rot, incomplete and other sowing diseases and insect pests, serious Affect the quality of sowing and reduce the rate of sowing seedlings
For example, peanut seedlings are infected by Fusarium and cause root rot, and mole crickets eat seeds and rhizomes, resulting in lack of seedlings and ridges in peanuts, seriously affecting yield

Embodiment 1

[0020] Embodiment 1: Indoor toxicity test

[0021] Peanut root rot test method: refer to the standard method of bioassay NY / T1156.2-2006, and use the method of medium containing medicine. Take 6mL of the drug solution of each single agent and mixed agent serial concentration, and add it to 54mL PDA medium cooled to 45°C to make a drug-containing medium plate with the required final concentration. Then, 6mm-diameter hyphae blocks were prepared from the edge of the peanut root rot pathogen colony cultured for 7 days, and moved to each series of drug-containing medium, with the hyphae facing down, and each treatment was repeated 4 times. After the treatment, they were cultured in a constant temperature biochemical incubator at 25±1°C.

[0022] Mole cricket test method: refer to the bioassay standard method NY / T1154.10-2008, and use the soil mixing method. Pass the dry sandy loam soil through a 40-mesh stainless steel sieve, carry out high-temperature disinfection treatment at 2...

Embodiment 2

[0033] Example 2: 24% fludioxonil · metalaxyl · cyantraniliprole suspension seed coating

[0034] The following substances are all in weight ratio: fludioxonil 2%, metalaxyl 2%, cyantraniliprole 20%, dodecylbenzenesulfonate 4%, octyl phosphate 2%, PVA0.2%, Brilliant Red 2%, Magnesium Aluminum Silicate 2%, Glycerol 2%, Potassium Sorbate 0.3%, Triethylamine 0.3%, Silicone 0.5%, Deionized Water to 100%. The above-mentioned materials are pre-crushed and stirred in proportion, added to a sand mill for grinding, and mixed by high shear to prepare a 24% fludioxonil·metalaxyl-fine·cyantraniliprole suspension seed coating agent.

Embodiment 3

[0035] Example 3: Seed Treatment Application

[0036] Selected peanut seeds are placed in a bucket for later use, measured according to the ratio of medicine: water: seeds (1:49:200), the medicine is fully diluted with water in advance, and the diluted medicine and seeds are fully stirred evenly. Leave to dry. After drying, follow the conventional sowing operation, and investigate the occurrence of diseases and insect pests and the number of peanut seedlings after the peanuts grow to the 4-leaf stage.

[0037] As can be seen from Table 3 and Table 4, 24% fludioxonil · metalaxyl · cyantraniliprole suspension seed coating agent treats peanut seeds, the control effect on peanut root rot is 97.32%, and the control effect on mole crickets is 95.15% , Improve peanut seedling growth by more than 59%, and it is safe for peanuts. The effect of 24% fludioxonil · metalaxyl · cyantraniliprole suspension seed coating was significantly better than that of single and binary combinations. ...

Abstract

The invention relates to a seed treatment composition containing cyantraniliprole, fludioxonil and metalaxyl-M. Effective components of the composition include fludioxonil, metalaxyl-M and cyantraniliprole and the mass ratio of fludioxonil to metalaxyl-M to cyantraniliprole is (1-10):(1-10):(1-20). The composition is used for coating treatment of peanut seeds, has a synergistic function on preventing root rot and mole crickets of peanuts, and increases the sowing seedling rate of peanuts.

Description

technical field [0001] The invention belongs to the technical field of pesticide combinations and applications, in particular to a peanut seed treatment composition, the active ingredients of which are fludioxonil, metalaxyl and cyantraniliprole, and the composition has a synergistic effect on preventing and treating peanut root rot and mole crickets , Improve the seedling rate of peanut seeds. Background technique [0002] In agricultural production, the quality of seeds directly affects the production of crops, and the seeds from germination to seedling stage are easy to be carried by seeds or infected by pathogenic bacteria in the soil, and gnawed by insects, causing rot, incomplete and other sowing diseases and insect pests, serious Affect the quality of sowing and reduce the rate of sowing seedlings. For example, fusarium infestation of peanut seedlings caused root rot, and mole crickets gnawed on seeds and rhizomes, resulting in lack of seedlings and ridges in peanuts...
