Embodiment 1

[0014] The preparation of embodiment 1 ricinine insecticide

[0015] 0.6% of ricinine, 0.2% of beta-cis-trans-cypermethrin, 0.15% of Tween 80, 0.2% of butanoic acid, and water as the balance, mix and stir each component according to the above weight percentage, and make ricinine insecticide .

Embodiment 2

[0016] The preparation of embodiment 2 ricinine insecticide

[0017] 2% ricinine, 1.8% beta-cis-trans-cypermethrin, 0.02% Tween 80, 0.1% butanobutanol, water as the balance, mix and stir each component according to the above weight percentage, and make ricinine insecticide .

Embodiment 3

[0018] The insecticidal experiment of embodiment 3 ricinine insecticide

[0019] Utilize the ricinine insecticide prepared in Example 1 to do the following insecticidal experiments.

[0020] Carry out a preliminary test first, design the concentration range of the test agent according to the results of the preliminary test, and prepare the required gradient concentration. Five concentrations were set for each of Spodoptera litura and Plutella xylostella, and water controls were set respectively, and 3 replicates were set for each concentration. Use a petri dish with a diameter of 9 cm, put filter paper in each petri dish, and place it about 15 cm according to the different test insects. 2 The fresh leaves of Spodoptera litura are taro leaves, and the test leaves of Plutella xylostella xylostella are cabbage leaves, and then the test insects are inserted. A Potter spray tower was used for double-sided quantitative spraying, each side was treated with 1ml of medicinal solution...

Abstract

An insecticide for killing plutella xylostella and noctuid is prepared from ricinine, alpha-cypermethrin, tween-80, piperonyl butoxide and water through proportional mixing.

Description

technical field [0001] The invention relates to the field of biological pesticides, in particular to a ricinine pesticide. Background technique [0002] Castor is a plant of the genus Castor in the family Euphorbiaceae. The largest producer is Brazil, followed by China and Thailand. Currently, the annual output of castor in the world is more than 900,000 tons. Castor oil, the main component of castor, is widely used in chemical, textile, light industry, and pharmaceutical departments to produce coatings, paints, soaps, inks, dyeing aids, accelerators, emulsifiers, etc. Castor beans contain a variety of toxins, such as ricin, ricinine, allergens, hemagglutinins, etc. The existence of these toxins has hindered the castor cake that contains 35~40% protein in the application of feed industry, causes the waste of a large amount of protein. Now people are trying to remove the toxic components in the castor cake, while a lot of research has been done on the mechanism of action an...
