Embodiment 1

[0013] Example 1: Toxicity determination of the combination of acetylspiramycin and abamectin to whitefly.

[0014] Vegetable whitefly was used in the test, and the toxicity index and co-toxicity coefficient (CTC value) of the mixture were calculated according to Sun Yunpei's method.

[0015] Table 1. Toxicity determination results of different ratios to vegetable whitefly

[0016]

[0017]

[0018] It can be seen from Table 1 that the co-toxicity coefficient of the combination of acetylspiramycin and abamectin is far greater than 130, which has a high synergistic effect.

Embodiment 2

[0019] Embodiment 2: 6% acetylspiramycin·abamectin aqueous emulsion.

[0020] Acetylspiramycin 1%, abamectin 5%, castor oil polyoxyethylene ether 5%, phenethylphenol polyoxyethylene ether 10%, dimethyl sulfoxide 6%, glycerin 4%, higher alcohol 1%, xanthan gum 3.5%, and the balance is water.

[0021] The preparation method is a conventional method in the art.

[0022] This embodiment medicament is applied to the prevention and treatment of golden leaf moth, and the co-toxicity coefficient is 135.4;

[0023] Mix 60 kilograms of water with the amount of drug preparation per mu for uniform spraying, add water to dilute the spraying by 3000 times, the control effect is 96.6% 15 days after the medicine, 1% acetylspiramycin suspension concentrate is diluted 500 times and 5% abamectin water The emulsion was diluted 2000 times and used in the same way respectively. After 15 days of application, the control effects were 62.1% and 82.2%, respectively, and the difference was significant...

Embodiment 3

[0024] Embodiment 3: 10% acetylspiramycin·abamectin aqueous emulsion.

[0025] Acetylspiramycin 2%, Abamectin 8%, Castor Oil Polyoxyethylene Ether 10%, Phenylphenol Polyoxyethylene Ether 5%, Dimethyl Sulfoxide 4%, Glycerol 4%, Higher Alcohol 1.5%, xanthan gum 4%, the balance is water.

[0026] The preparation method is a conventional method in the art.

[0027] This embodiment medicament is applied to control leaf miner, and the co-toxicity coefficient is 270.5;

[0028] Mix 60 kilograms of water with the amount of drug preparation per mu for uniform spraying, add water to dilute the spraying by 3000 times, the control effect is 98.4% 15 days after the medicine, 2% acetylspiramycin suspension concentrate is diluted 500 times and 8% abamectin water The emulsion was diluted 2000 times and used in the same way respectively. After 15 days of application, the control effects were 79.5% and 82.6%, respectively, and the difference was significant.

Abstract

The invention discloses insecticidal water emulsion containing acetylspiramycin, wherein effective ingredients are the acetylspiramycin and agricultural insecticide, the weight ratio of the acetylspiramycin to the agricultural insecticide is 1: (1-1) :5, and the weight percentage of the acetylspiramycin to the agricultural insecticide in the water emulsion is 5-10%. Active ingredients of the agricultural insecticide are selected from one or two of abamectin, chlorpyrifos, lambda-cyhalothrin, beta-cypermethrin and triazophos. The insecticidal water emulsion has a good contact action on multiple crop pests, agentia has lipotropy performance, high efficiency is achieved for adult or weak pests, beneficial insects are not killed or damaged, pests do not generate resistance easily, and a insecticidal spectrum is wide; by means of the insecticidal water emulsion, consumption of pesticide is reduced, the prevention and treatment effect is improved, the current problem of pest resistance to insecticide is relieved to the maximum degree, the purpose of protecting crops is achieved, the yield can be raised, and quality can be improved.

Description

technical field [0001] The invention belongs to the technical field of pesticides, and specifically relates to an application technology of acetylspiramycin in insecticidal aqueous emulsion. Background technique [0002] Acetylspiramycin is an antibiotic with a macrolide structure. It is a low-toxicity, low-residue, broad-spectrum insecticide that can prevent and control various crop pests, and has a good control effect. It has good contact killing effect on a variety of crop insect pests, has no systemic property, and the agent is lipophilic. It is highly effective against adult and weak insects, does not kill beneficial insects, and it is difficult for pests to develop resistance. Leaf miner, leaf miner, vegetable whitefly and other pests are all effective, and compounded with some organophosphate or carbamate pesticides, there is a significant synergistic effect. The contact effect of the harmful punch is valid for 7-14 days. [0003] Acetylspiramycin is a mixture of fo...
