Embodiment 1

[0016] In order to prevent rice leaf rollers and mites in agriculture, delay and overcome the emergence of drug resistance, we have conducted research on the synergistic effect of compounding chlorfenapyr, lambda-cyhalothrin and other ingredients. The test uses the rice leaf roller and Tetranychus cinnabarinus as test objects in the field, and the specific method is as follows:

[0017] For the control of rice leaf roller, the test agent is the original drug provided by the manufacturer, and the research department of our company formulates the required preparations. The test insects are the rice leaf roller pupae collected from the field, and they are raised indoors for three generations. The three generations with uniform growth are selected Instar larvae are inserted into a 9-centimeter petri dish with a diameter of 9 centimeters of fresh paddy rice leaves (Shanyou 63, five-leaf stage), and every dish connects 10 heads, and every process connects six dishes, spraying under 5...

Embodiment 2

[0022] To prevent and control Tetranychus cinnabarinus, the test agent is the original drug provided by the manufacturer, and the research department of our company prepares the required preparations. The test insects are female adults of Tetranychus cinnabarinus collected from the field. After three generations of indoor breeding, the adult mites with uniform growth are selected , access the petri dish with a diameter of 9 cm in which the cotton leaves are placed, and each dish is connected with 30 heads, and each treatment is connected with three dishes, sprayed with a POTT spray tower at a pressure of 50PSI, one dish is sprayed at a time, and each dish is sprayed with 3 ml. The blank control was sprayed with the same amount of water. Generally, 5 concentration gradients were set for each treatment. The treated culture dishes were cultured in a 25°C, 12H / 12H light incubator, and the number of surviving insects was checked for 48 hours to calculate the population decline rate....

Embodiment 3

[0027] Control rice leaf roller (proportion by weight)

[0028] According to 5 parts of chlorfenapyr, 3 parts of lambda-cyhalothrin, 16018 parts of emulsifier, 6 parts of emulsifier 500#, and the balance is toluene, it is prepared into emulsifiable concentrate. The formula is diluted and sprayed by 2000 times, and the control effect is 100% 72 hours after application. 10 parts of chlorfenapyr EC and 5 parts of lambda-cyhalothrin EC are used in the same way, and the control effects of 72 hours after application are 52.3% and 100%, respectively. 34.0%.

Abstract

The invention relates to a composite drug, which comprises carbofuran and high-effect cypermethrin at 1:2-20:1. The invention can effectively kill pests.

Description

technical field [0001] The invention relates to pesticides, in particular to a compound pesticide containing chlorfenapyr and lambda-cyhalothrin. Background technique [0002] Chlorfenapyr, also known as chlorfenapyr, is a new type of insecticide and acaricide, which is used to control important agricultural pests such as beet armyworm, Spodoptera litura, Diamondback moth, Pieris rapae, etc. Mites such as Tetranychus urticae and Tetranychus cinnabarinus also have good control effects. [0003] Lambda-cyhalothrin is a pyrethroid insecticide used to control agriculturally important pests such as beet armyworm, Spodoptera litura, Diamondback moth, Pieris rapae, etc. It also has certain effects on mites. The pest is mainly through the contact action. [0004] In the actual process of agricultural production, the most likely problem in the control of pests is the emergence of pest resistance. The rice leaf roller is a common pest that harms rice and often causes serious disaste...
