specific Embodiment 1

[0021] Specific embodiment 1: the test of controlling cauliflower aphid and cabbage caterpillar with the insecticide that above-mentioned embodiment makes.

[0022] (1) Test crop: cauliflower, the variety is "Songhua 90" 30 mu, 2400 plants per mu field; (2) Test treatment: This test is a production comparison test, and a biological insecticide control area and a customary control area ( control area). Spray with 200 grams of the above-mentioned biological insecticide mixed with 30 kg of water per mu in the biological insecticide control area, and spray with chlorantraniliprole (Sword) 30 ml per mu mixed with 30 kg of water in the customary control area;

[0023] (3) Test method: The biological pesticide control area and the customary control area are sprayed at the same time, the number of pests in the field is investigated before spraying, the spray quality is guaranteed when spraying, the front and back of the leaves are sprayed evenly, and there is no rainfall within 10 day...

specific Embodiment 2

[0027] Specific example 2: the test of preventing and controlling cabbage cabbage caterpillar with the above-mentioned biological system insecticide.

[0028] (1) Test treatment: refer to the standards of the People's Republic of China (Guidelines for Field Efficacy Tests of Pesticides). In this test, three treatment concentrations were set according to the different components (group A 167 g / mu, group B 200 g / mu, group C 233 g / mu, all mixed with water 30 kg / mu). The control group was blank water test.

[0029] (2) Test method: The area of ​​each plot is 30 square meters, repeated 4 times, the biological pesticide control area and the control area are sprayed at the same time, the base of field pests is investigated before spraying, and the spray quality is guaranteed when spraying.

[0030] (3) 5 days after spraying, use the checkerboard survey method to control the biological pesticide control area and the control area, and 10 days after spraying, use the checkerboard surve...

specific Embodiment 3

[0033] Specific embodiment 3: the test of preventing and treating black spot of Chinese cabbage with above-mentioned biological system insecticide.

[0034] (1) Test treatment: The test set two treatments of the above-mentioned biological insecticide 240 g / mu (treatment A) and a blank control, and sprayed with 45 kg of water per mu;

[0035] (2) Test method: Random block design was adopted, repeated 3 times, each plot was 30 square meters, and protection rows were set between plots;

[0036] (3) In the early stage of the onset of black spot of Chinese cabbage (Chinese cabbage rosette stage), it was sprayed with a hand-pressed spray in late August, and the disease index was investigated after the medicine (condition classification: 0: no disease spots on the whole leaf; There are sporadic lesions, accounting for less than 25% of the leaf area; Grade 2: the area of ​​lesions on the leaves accounts for 26%-50% of the leaf area; Grade 3: the area of ​​lesions on the leaves account...

Abstract

The invention provides plant pesticide and a preparation method and application thereof. The plant pesticide is prepared from aralia chinensis and pterocarya stenoptera. The preparation method includes: putting raw materials into a reaction kettle, and injecting water according to a solid-liquid weight ratio of 1:4; using an electric heating steam generator to heat for 4h to 80 DEG C, and enteringa centrifugal machine for separation of liquid and residue; concentrating the liquid to obtain the plant pesticide. The plant pesticide has the advantages that the plant pesticide can effectively inhibit common fruit-vegetable pest like cabbage caterpillar, aphid, plutella xylostella, prodenia litura, red spider and empoasca flavescens, and one-time killing rate is up to higher than 80%; the plant pesticide has certain prevention and control effect on the common fruit-vegetable pest like alternaria brassicae.

Description

technical field [0001] The invention belongs to the technical field of pesticide preparation, and specifically relates to a plant pesticide and a preparation method thereof. Background technique [0002] At present, chemical pesticides are mostly used to prevent and control agricultural pests. With the improvement of people's living standards, people have higher requirements for the quality of agricultural products. They must not only eat well, but also eat healthily. The problem of pesticide residues caused by highly toxic chemical pesticides has increasingly become a hot spot of social concern. Highly toxic pesticides are the core and key to affecting the quality and safety of agricultural products. They not only affect the quality of agricultural products, but also directly endanger the health of the people, and also affect the increase of farmers' income. Due to the high toxicity of highly toxic pesticides, incidents of human and animal poisoning have occurred from time...
