[0002] Rice planthopper (including rice planthopper, SBPH, white-backed planthopper) is a species with strong migratory ability (except SBPH), with a very high intrinsic growth rate, and the population often grows rapidly when conditions are suitable. Therefore, chemical control is the most effective way to control the rice planthopper population. Since the 1980s, buprofezin, imidacloprid, organophosphorus and their compound agents have been the main control agents, and they have played an important role in rice production. It plays an important role, especially in the mid-1990s, the new ultra-high-efficiency chlorinated neonicotinoid insecticide - imidacloprid, has good quick-acting, long-lasting effect, low dosage, low toxicity to humans and animals and is harmless to the environment. Compatibility, and quickly became the leading pesticide variety for the control of rice planthoppers. Due to long-term single and large-scale continuous use, it is equivalent to extensive resistance screening of rice planthoppers in the field. Rice planthoppers have obvious resistance to imidacloprid, and the control effect At present, there is a shortage of pesticide varieties to effectively control rice planthoppers in rice production. Although there are new pesticide varieties introduced, the cost of control is too high, and the use of a single pesticide variety makes rice planthoppers prone to develop resistance

Embodiment 1
[0010] Example 1: 30.5% Pentamicloguanidine Etofenproxil Water Dispersible Granules
[0011] 0.5g Pentaclofen, 30g Etofenprox, 4g Sodium Lauryl Sulfate, 2g Lauryl Polyoxyethylene Ether, 2g Lignosulfonate, 2g Sulfonic Acid Polyoxymethylene Condensate (NNO), 2g Polyethylene glycol Alcohol, 4g of ammonium sulfate, 10g of sodium carboxymethylcellulose, and kaolin were supplemented to 100g to prepare 30.5% pentafenguanidine etofenproxil wettable powder.
Embodiment 2
[0012] Example 2: 30.5% Pentamicloguanidine Etofenproxil Water Dispersible Granules
[0013] 30g Pentaclofen, 0.5g Etofenprox, 4g Sodium Lauryl Sulfate, 2g Lauryl Polyoxyethylene Ether, 2g Lignosulfonate, 2g Sulfonic Acid Polyoxymethylene Condensate (NNO), 2g Polyethylene glycol Alcohol, 4g of ammonium sulfate, 10g of sodium carboxymethylcellulose, and kaolin were supplemented to 100g to prepare 30.5% pentafenguanidine etofenproxil water-dispersible granules.
[0014] According to the formula of Examples 1 and 2, the active ingredients, additives, and carriers are mixed, and after stirring evenly, the mother powder is obtained by crushing, and the mother powder and the binder are mixed evenly, and then granulated, dried, and sieved, that is 30.5% imidacloprid and etofenproxil water dispersible granules can be prepared.

Abstract
The invention discloses a compound insecticide containing pentaclofen, which belongs to the technical field of pesticide control. The weight ratio of pentaclofen and etofenprox is 1:60-60:1. Its composition also contains adjuvants and carriers, wherein pentaclofen and etofenproxil account for 5%-60% of the total weight of the insecticide, the auxiliaries account for 5%-30% of the total weight of the insecticide, and the rest are carrier. The insecticide of the present invention has a significant control effect on rice planthoppers through actual testing. Compared with conventional insecticides, the compound insecticide of the present invention has the following advantages: compared with a single agent, the variety has obvious synergistic effect on rice planthoppers, which can significantly improve the control effect; it can replace some medium and high toxicity insecticides It can reduce the dosage, environmental pollution and residues of agricultural products; it can delay the resistance of rice planthoppers to a single insecticide, and has the advantage of long-lasting effect. Compared with a single agent, it can reduce the cost.
