Problems solved by technology

The study found that the anti-platelet aggregation activity was proved by the rat platelet aggregation experiment induced by ADP in vitro, and the inhibition rate was 24.5±11.3% under the condition of the final concentration of 1mg / mL; the rat pituitary GH 3 Cell depolarization-induced Ca 2+ Inhibits absorption with calcium channel blocking activity at least as potent as verapamil; inhibits pituitary GH in rats 3 Cells release prolactin; anti-inflammatory effect, the dose is 10mg / kg, it has obvious anti-inflammatory activity; when the dose is 10μM, it significantly inhibits DNA topoisomerase II, ID 50 <10μM; In addition, when the dose is 10mg / Kg, it shows obvious analgesic activity; Dihydro-ogeeol angelate has good medicinal activity, but so far there is no dihydro-ogeeol angelate used as an insecticide in on agricultural production

Embodiment 1

[0012] Example 1 Prevention and control of agricultural pests with dihydro-salveol angelate as an 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 dihydro-salverol angelate (purchased from China 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 filte...

Embodiment 2

[0018] The wettable powder with active ingredient concentration of 5% was prepared by weighing dihydro-salveol angelate, lignin, diatomaceous earth and other conventional auxiliary materials according to the conventional process.

Embodiment 3

[0020] Weighing conventional excipients such as dihydropiperol angelate, calcium dodecylbenzenesulfonate, phenethylphenol polyoxyethylene ether, solvent oil, etc., according to a conventional process, to prepare an emulsifiable concentrate with an active ingredient concentration of 5%.

Abstract

The invention discloses a use of Columbianadin as an agricultural pesticide and an agricultural insect antifeedant. The Columbianadin which serves as the pesticide and the insect antifeedant has an obvious effect in prevention and control of both Lepidoptera and homopteran insects. Furthermore, the Columbianadin serving as the agricultural insecticide further has the characteristics of low toxicity, no residue, no pollution and no public nuisance, and is more beneficial to environment protection.

Description

technical field [0001] The invention belongs to the technical field of agriculture, and in particular relates to the use of dihydro-salveol angelate as an active ingredient in the preparation of agricultural insect feed repellents and insecticides. 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 pestici...
