Problems solved by technology

In order to expand the insecticidal spectrum of botanical pesticides and further improve the application effect of botanical pesticides, some people in China have compounded botanical pesticides with different properties to expand the insecticidal spectrum (Hunan Normal University Biological Experimental Factory, 2001; Tianjin Shengli Plant Pesticide Factory, 2005; Yunnan Wenshan Runze Biological Pesticide Factory, 2008), although some results have been achieved, they are not very satisfactory

Embodiment 1

[0009] The active ingredients are as follows by weight ratio: 10 parts by mass of nicotine, 1 part by mass of picroderm, 10 parts by mass of emulsifier (2201), 2 parts by mass of synergist (azone), 77 parts by mass of solvent (xylene) . First add most of the solvent to the preparation tank, and then add nicotine, picroderm, emulsifier, synergist and the rest of the solvent in sequence according to the conventional usage amount while stirring. Then add 0.2-0.3 parts by mass of 60-80 mesh diatomite (filter aid) and filter to obtain the synergist insecticide.

Embodiment 2

[0011] Wherein the active ingredients are by weight: 20 parts by mass of nicotine, 0.6 parts by mass of picroderm, 10 parts by mass of emulsifier (2201), 2 parts by mass of synergist (azone), 67.4 parts by mass of solvent (xylene) . First add most of the solvents to the preparation tank, then add nicotine, picroderm, emulsifier, synergist and the remaining solvent in sequence according to the conventional usage amount under stirring, then add 0.2- The insecticide is obtained by filtering 0.3 parts by mass of 60-80 mesh diatomite (filter aid).

Embodiment 3

[0013] The active ingredients are as follows by weight: 30 parts by mass of nicotine, 0.2 parts by mass of picrodine, 10 parts by mass of emulsifier (2201), 2 parts by mass of synergist (azone), 57.8 parts by mass of solvent (xylene) . First add most of the solvent into the preparation tank, and then add the nicotine, picroderine, emulsifier, synergist and the remaining solvent in sequence according to the above-mentioned amount under the condition of stirring. Finally, 0.2-0.3 parts by mass of 60-80 mesh diatomite (filter aid) is added for filtration to obtain the insecticide.

[0014] The use method of the insecticide of the present invention is, for the Homoptera pest (aphid, leafhopper, whitefly etc.) Inchworm, etc.), apply at the 2-3 larval stage, use the insecticide of the present invention mixed with 1500 times of water to spray the stems and leaves, and must be sprayed evenly. For the older larvae of Lepidoptera pests (Pipella rapae, larvae of boat moth, and inchworm...

Abstract

The invention discloses a plant source compound insecticide, which is prepared from the following components in parts by mass: 10-30 parts of nicotine, 0.2-1.0 part of celastrus angulatus, 110 parts of farming dairy 220, 2 parts of azone, 57.8-77 parts of dimethylbenzene and 0.2-0.3 part of diatom. Compared with the prior art, the plant source compound insecticide has the obvious advantages of good insect-killing effect and wide insecticidal spectrum.

Description

[0001] Technical field: [0002] The invention relates to an insecticide, in particular to a compound insecticide derived from plants. Background technique: [0003] At present, the domestic area of ​​vegetables, fruit trees and flowers is getting larger and larger. Homopteran pests (aphids, leafhoppers, mealybugs, etc.) and Lepidoptera pests (rape rapae, boat moth larvae, inchworms, etc.) on these plants have caused serious damage, which has become a problem in production. The botanical pesticides currently used in production have a relatively narrow insecticidal spectrum, and some have better control effects on Homopteran pests, such as nicotine, matrine, anartemisinin, etc. Some have a better control effect on Lepidoptera pests, such as hornitine and ryanodine. In order to expand the insecticidal spectrum of botanical pesticides and further improve the application effect of botanical pesticides, some people in China have compounded botanical pesticides with different p...
