Embodiment 1

[0012] Embodiment 1 Violet Procurdin is used as an active ingredient in the prevention and control of agricultural pests

[0013] The source of the tested insects was the 3rd to 6th instar larvae collected from the field population, raised indoors with artificial feed until pupation and oviposition, and the 2nd to 3rd instar larvae of the F1 and F2 generations in the room were selected for toxicity testing (including Pieris rapae collected for field populations). Accurately weigh Prostinol (separated and purified from Umbelliferae plant Peucedanum, the purity measured by HPLC peak area normalization method reaches more than 98%), dissolve it in acetone, and make the concentration of 2.000mg / mL of the test mother solution, and then diluted with 1% TritonX-100 water emulsion into 6 different concentrations as the test drug solution for later 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 o...

Embodiment 2

[0018] The wettable powder with active ingredient concentration of 1% is prepared by weighing conventional excipients such as procuredin, lignin and diatomaceous earth according to the conventional process.

Embodiment 3

[0020] Weighing conventional excipients such as procuratin, calcium dodecylbenzenesulfonate, phenethylphenol polyoxyethylene ether, solvent oil, etc., according to the conventional process, to prepare an emulsifiable concentrate with an active ingredient concentration of 1%.

Abstract

The invention discloses application of decursin as agricultural insecticide. The decursin serving as insecticide has remarkable effect in preventing and controlling lepidoptera and homoptera insects. Furthermore, the decursin serving as the agricultural insecticide has the characteristics of low toxicity, no residue, no pollution and no nuisance, and is more advantageous to environmental protection.

Description

technical field [0001] The invention belongs to the technical field of agriculture, and in particular relates to the use of proscurdin as an active ingredient in the preparation of 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 pesticides. [0004] Purple Flower Precursin, English name D...
