Embodiment 1

[0012] Embodiment 1 Angelica sinensis is used as the control of agricultural pests as active ingredient

[0013] The source of the tested insects was the 3rd to 6th instar larvae collected from the field population and raised indoors with artificial feed until they pupated and oviposited, and the 1st instar larvae whose F1 and F2 generations were basically the same in size were selected for the virulence test. Accurately weigh Angelica sinensis (purchased from China National Institute for the Control of Pharmaceutical and Biological Products), dissolve it in acetone, and prepare a concentration of 1.000 mg / ml as a test liquid for future use. Use a leaf topper to make fresh and clean cabbage leaves (wherein the armyworm uses wheat leaves) into a leaf disc with a diameter of 1.5 cm, then soak it in the test drug solution for 10 seconds, take it out, and then take it out and dry it in a place containing Into the culture dish of 1% water agar or moisture-retaining filter paper, in...

Embodiment 2

[0018] Weigh white angelica element, lignin, diatomaceous earth and other conventional auxiliary materials according to the conventional process to prepare a wettable powder with an active ingredient concentration of 5%.

Embodiment 3

[0020] Weighing conventional excipients such as angelica element, calcium dodecylbenzenesulfonate, styrene ethylphenol polyoxyethylene ether, mineral spirits and so on, according to the conventional process, to make an emulsifiable concentrate with an active ingredient concentration of 5%.

Abstract

The invention discloses an application of byakangelicin used as an agricultural pesticide and an insect antifeedant. The byakangelicin has an obvious effect of preventing and controlling lepidopterous insects and homoptera when being used as the pesticide and the insect antifeedant, and also has the characteristics of low toxicity without any residues or pollutions when being used as the agricultural pesticide, so that environmental protection is favored.

Description

technical field [0001] The invention belongs to the technical field of agriculture, and specifically relates to the use of angelica element as an active ingredient in the preparation of an agricultural insect antifeedant and an insecticide. Background technique [0002] Agricultural pests occur in a large area in many areas of our country, and the frequency is on the rise, and the damage is aggravated. At present, chemical pesticide control is still the main control measure. Due to the long-term use of chemical pesticides, the pests have developed varying degrees of resistance to various chemical insecticides such as organochlorines, organophosphorus, carbamates, and pyrethroids, and the control effect has declined significantly, forcing farmers to increase The dosage is to improve the control effect, but it reduces the safety of agricultural products. [0003] Therefore, it is particularly important to explore efficient, safe and environment-friendly green pesticides. ...
