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 Control of agricultural pests with dihydroparcelyl angelate as an active ingredient

[0013] The source of the tested insects was the 3-6 instar larvae of the collected field population, which were raised indoors with artificial feed to pupate and lay eggs. The first instar larvae with the same size of F1 and F2 generations were selected for the determination of virulence. Accurately weigh dihydroparsylol angelate (purchased from the National Institute for the Control of Pharmaceutical and Biological Products), dissolve it in acetone, and make a concentration of 1.000 mg / ml as the test drug solution. Use a leaf breaker to make fresh and clean cabbage leaves (wheat leaves for armyworms) into leaf discs with a diameter of 1.5 cm, and then soak them in the test solution for 10 seconds, then take them out, then take them out and dry them in the In a petri dish of 1% water agar or moisturizing filter paper, insert the test insects starved for 3 h, and place them in an...

Embodiment 2

[0018] Weigh dihydroparsyl alcohol angelate, lignin, diatomaceous earth and other conventional auxiliary materials according to conventional techniques to prepare a wettable powder with an effective ingredient concentration of 5%.

Embodiment 3

[0020] Weigh dihydroparsyl alcohol angelate, calcium dodecyl benzene sulfonate, phenethyl phenol polyoxyethylene ether, solvent naphtha and other conventional auxiliary materials to prepare emulsifiable concentrate with an effective ingredient concentration of 5% according to conventional techniques.

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 particularly relates to the use of dihydroparsyl alcohol angelate as an active ingredient to prepare agricultural insect antifeedants and insecticides. Background technique [0002] Agricultural pests occur on a large scale in many areas of our country, and the frequency is increasing, and the damage is increasing. The main control measures are still the prevention and control of chemical pesticides. Due to the long-term use of chemical pesticides for prevention and control, the pests have developed resistance to various chemical pesticides such as organochlorine, organophosphorus, carbamate, pyrethroids, etc., and the control effect is significantly reduced, which makes farmers have to increase The dosage is used to improve the control effect, but it reduces the safety of agricultural products. [0003] Therefore, it is particularly important to explore efficient, safe and environmentally fri...
