Embodiment 1

[0014] Example 1: Toxicity determination of abamectin, pyraclofen and flufenuron and different ratios to Panonychus citrus

[0015] The test method refers to the "People's Republic of China Agricultural Industry Standard NY / T1154.12-2006". The female adults of Panonychus citrus collected from the field were reared indoors for 30 generations, and the female adults with uniform growth were selected as the test insects. Adopt the small seedling method, that is, inoculate 50-60 heads of all claw mites on small pots of citrus seedlings, check the base number one day later, pick out dead mites, and add live adult mites, and keep the number of mites for each treatment at about 50. Spray the seedlings with mites using a spray tower, move them to culture at 25°C and 90% relative humidity, check after 15 days, record the number of survivors, use DPS data processing software for statistical analysis, calculate the regression curve, and calculate the LC 50 , using the co-toxicity coeffic...

Embodiment 215

[0025] The preparation method of embodiment 215% abamectin, pyraclofen, flubenzuron suspension concentrate and medicament field test

[0026] Weigh 2% abamectin, 8% pyraclofen, 5% flubenzuron, 4% alkylphenol formaldehyde resin polyoxyethylene ether (dispersant), 3% alkylphenol polyoxyethylene ether phosphate ( Wetting agent), 1.5% polyvinyl alcohol (thickener), 0.3% silicone defoamer, deionized water added to 100% by weight. The above raw materials were mixed, dispersed at high speed for 30 minutes, and sand-milled with a sand mill to prepare a 15% abamectin·pyrafenoxate-flubenzuron suspension concentrate.

[0027] The field efficacy test of the prepared 15% Abamectin · Fenfluben · Flubenzuron suspension concentrate on the control of citrus spider mites was conducted to verify the control effect, effective dosage and safety of the agent on citrus spider mites. , The test site is Guangyuan, Sichuan, and the control object is citrus spider mite. The conventional method is used ...

Embodiment 312

[0035] Embodiment 312% Abamectin · Fenfluben · Flubenzuron microemulsion preparation method and medicament field test

[0036] Weigh 1.0% abamectin, 6.0% pyraclofen, 5.0% flubenzuron, 4% octylphenol polyoxyethylene ether (emulsifier), 5% alkylphenol formaldehyde resin polyoxyethylene ether (dispersant) , 5% calcium dodecylbenzenesulfonate (emulsifier), 15% cyclohexanone (solvent), 5% N-methylpyrrolidone (solvent), 5% n-butanol (emulsifier), 1% epoxy Chloropropane (stabilizer) is completely dissolved and mixed evenly, and deionized water is added to 100% by weight, and after stirring, a 12% abamectin-pyramid-flubenzuron microemulsion is obtained.

[0037] The field efficacy test of the prepared 12% abamectin·pyrafenoxate·flubenzuron microemulsion against citrus spider mites was verified to verify the control effect, effective dose and safety of the agent on citrus spider mites. , the test object is Panonychus citrus, and during the test, Panonychus citrus has more adult mites,...

Abstract

The invention relates to a pesticide composition containing abamectin, fenpyroximate and flufenoxuron as active components. The pesticide composition is characterized in that the weight ratio of abamectin to fenpyroximate and flufenoxuron is (1-2):(6-9):(5-9). In the pesticide composition, the acting mechanisms of abamectin, fenpyroximate and flufenoxuron are different, and an obvious synergistic effect is achieved through reasonable mixing of abamectin, fenpyroximate and flufenoxuron, so that the pesticide effect can be greatly improved, and the pesticide consumption per mu can be reduced. Therefore, the adverse influence on the environment and the amount of a pesticide residue are reduced, the pesticide effect duration is prolonged, and the defect that a single pesticide agent cannot cover all growth cycles of red spiders is overcome.

Description

technical field [0001] The invention relates to a pesticide composition, in particular to an acaricidal composition containing pyraclofen and flufenuron, which is used for preventing and controlling harmful mites of citrus trees. Background technique [0002] In recent years, with the continuous increase of the market price of citrus, the planting area of ​​citrus has also been expanding, so frequent drug use and increasing dosage are becoming more and more common. At present, the main pests that harm citrus are red spiders. Citrus red spiders are also known as panonychus citrus. Adults, nymphs, and young mites gather on leaves, twigs, and peels to absorb juice. The damaged leaves show many small gray spots, which are serious Sometimes the whole leaves are off-white, resulting in a large number of fallen leaves and dead shoots, affecting tree vigor and yield. When the fruit is harmed, the surface of the fruit is covered with off-white chlorotic spots, and the whole fruit is...
