Problems solved by technology

[0004] Abamectin is a biological pesticide, which is a sixteen-membered macrolide antibiotic, which mainly interferes with and blocks the nerve conduction of pests and pest mites, so that the pests will be paralyzed after application, refuse to eat and stop doing harm. High, highly effective against mites, pear psyllids, Liriomyza sativae, etc., but not effective against noctuid pests such as beet armyworm and Spodoptera litura

Embodiment 1

[0024] The results of the synergistic assay showed that the ratios of fetabol and abamectin were 20:1, 10:1, 5:1 and 3:1 for the combination of Spodoptera littoralis, Spodoptera litura, Plutella xylostella, and rice The co-toxicity coefficient of leaf borer and mites (red spiders) was 149-226, indicating that the combination of the two pesticides has a significant synergistic insecticidal effect on the above-mentioned pests.

Embodiment 2

[0033] The field test to Spodoptera exi 10ml), the insecticidal effect on Spodoptera exigua is 91-96%; while the compound of 0.25 g of statin + 0.15 g of abamectin for mu (that is, 5:3 for mu use) 5% compound agent 8ml), the insecticidal effect on beet armyworm is 88-93%, which are extremely significant (up to 1% significant level, the same below) higher than the insecticidal effect of 0.4 g of single agent of taibao per mu ( 58-67%) or the effect of 0.25 g of abamectin (72-75%). 15 days after the application, the insecticidal effects of the two compounds were 88-93% and 85-93%, respectively, which were also significantly higher than the insecticidal effects of 0.4 g of fentanyl per mu (52-63%) or Avitamin. The effect of 0.25 g of bacteriocin (72-75%).

Embodiment 3

[0035] Experiments on the control of 2 to 5-year-old mixed-age Spodoptera litura in the field show that 6 days after application, the compound agent of 1.0 g of statin and 0.05 g of abamectin (that is, 5% compound of 20:1 per mu was used) was used. preparation 21ml), the insecticidal effect on Spodoptera litura is 93-98%, which is significantly higher than the effect of 1.0 g of taibao per mu (81-90%), and extremely significantly higher than that of 0.05 g of abamectin per mu. effect (26-34%). 15 days after the application, the insecticidal effect of the compound was 88-97%, which was also significantly higher than the effect of 1.0 g of quintabol per mu (75-84%), and extremely significantly higher than that of abamectin 0.05 per mu. gram of insecticidal effect (20 ~ 28%).

Abstract

The present invention relates to a light-effective low-toxic multifunctional composite insecticidal and acaricidal preparation. It is formed from two active components of chlorfluazuron and abamectin and adjuvant and solvent. By pure dosage for every mu said composite preparation contains 0.1-5 g of chlorfluazuron and 0.05-2 g of abamertin. It can be used for controlling asparagus fern caterpillar, cotton worm moth, cabbage moth, rice leaf roller and red mite, etc.

Description

1. Technical field [0001] The invention belongs to the technical field of pest control, and in particular relates to a high-efficiency, low-toxicity and multi-functional insecticide compounded by the biomimetic insecticide Chlor-fluazuron and the biological insecticide Abamectin. Acaricides are used to effectively control vegetable pests such as Beet armyworm, Spodoptera litura, Plutella xylostella, and rice pests such as rice leaf roller, diploid, and trilober, as well as mites. 2. Technical background [0002] With the improvement of people's living standards, the demand for green agricultural products, especially green food, is getting stronger and stronger. Vegetables, rice and fruits are indispensable consumer products for people to eat three meals a day. The prevention and control of pests and mites has long relied on chemical pesticides, resulting in high pesticide residues in agricultural products and the environment, resulting in health hazards and environmental pol...
