Embodiment 1

[0015] Embodiment 1: Determination of indoor toxicity of fenflunomide, matrine and their mixtures to Panonychus citrus

[0016] The test method refers to the "People's Republic of China Agricultural Industry Standard NY / T1154.12-2006". The female adult mites collected from the field were reared indoors for 30 generations, and the female adult mites with uniform growth were selected as the test insects. The small seedling method was adopted, that is, 50-60 Panclaw mites were connected to the citrus seedlings in small pots, and the base number was checked after 1 day. The seedlings with mites were sprayed with a spray tower, moved to 25° C. and cultured at a relative humidity of 90%, checked after 15 days, and the number of survival was recorded.

[0017] LC calculation with DPS software 50 and toxicity regression equation, referring to NY / T1154.7-2006, Sun Yunpei’s method was used to calculate the co-toxicity coefficient (CTC) of each mixing ratio, and the synergistic effect ...

Embodiment 2

[0024] Example 2: 5.1% fenflunomide·matrine suspension agent

[0025] Weigh 4.8% of fenflunomide, 0.3% of matrine, 2.5% of alkylphenol formaldehyde resin polyoxyethylene ether (dispersing agent), and 3% of alkylphenol polyoxyethylene ether phosphate (wetting agent) , polyvinyl alcohol 1.5% (thickener), silicone 0.2% (defoamer), deionized water was added to 100% by weight. The above-mentioned raw materials are mixed, dispersed by high-speed shearing for 30 minutes, and then sanded with a sand mill to obtain a 5.1% fenflunomide·matrine suspending agent.

Embodiment 3

[0026] Example 3: 21.0% buflufenacil·matrine suspending agent

[0027] Weigh 20% of fenflunomide, 1.0% of matrine, 4.2% of naphthalene sulfonate formaldehyde condensate, 5% of sodium lauryl sulfate, 0.12% of silicone, 0.12% of gum arabic, deionized water Add to 100%, add water to 100% by weight. The above-mentioned raw materials are mixed, dispersed by high-speed shearing for 30 minutes, and then sanded with a sand mill to obtain a 21.0% fenflunomide·matrine suspending agent.

Abstract

The invention relates to a mite-killing compound containing cyflumetofen and sophocarpidine. The active ingredients contain cyflumetofen and sophocarpidine, wherein the mass ratio of cyflumetofen to sophocarpidine is (5-20):1. The two active ingredients of the mite-killing compound provided by the invention have a synergic effect; when the mite-killing compound is used for preventing and controlling citrus red mite, the resistance development of the insects can be delayed, the dosage of each single agent can be reduced and the preventing and control effect can be promoted; the mite-killing compound meets the requirement on comprehensive treatment of insects.

Description

technical field [0001] The invention relates to the technical field of pesticide application, in particular to an acaricidal composition containing buflufenafen and matrine, which is used for preventing and controlling harmful mites of citrus trees. Background technique [0002] In recent years, with the continuous increase of the price of citrus, the citrus planting area is also expanding. one. Due to the short generation period, strong fecundity, rapid population growth, high frequency of control and medication, and improper use, the citrus mites have developed resistance to the drugs with abamectin as the active ingredient, and the control effect has decreased significantly. Therefore, research and development of new high-efficiency, low-toxicity, and environment-friendly acaricides are of great significance for citrus production. [0003] Matrine, English name: Matrine, is a botanical pesticide with low toxicity to humans and animals, safe to use, no residue, stomach t...
