Embodiment 1

[0024] Indoor toxicity test

[0025] 1. Drug preparation

[0026] 5% dipropacyclopyrene dispersible liquid, provided by BASF, diluted to 10000mg / L mother liquor for later use. 1% matrine soluble liquid, provided by Huludao Pengxiang Pesticide Chemical Technology Co., Ltd., diluted into 10000mg / L mother liquor for later use.

[0027] The mass ratios of dipropetran and matrine are respectively 1:1, 2:1, 4:1, 10:1, 20:1, 40:1, 60:1, 80:1, and 100:1. For compound insecticides, each single agent and compound agent are diluted into 5-7 concentration gradients.

[0028] 2. Processing method

[0029] Using leaf dipping method. Dilute each test agent into 5-7 concentration gradients, select tender green tea leaves with nymphs of blackthorn whitefly, examine 50 third-instar nymphs under a microscope, and remove excess or dead nymphs with a brush. Soak the leaves in the pre-prepared medicinal solution for 5 seconds, take them out to dry, and put them into a petri dish. Each treatme...

Embodiment 2

[0047] Field efficacy evaluation test

[0048]According to the indoor toxicity determination test, the optimal ratio is 4:1, and it is formulated as a 2.5% dipropetran-matrine compound insecticide, which contains 2% dipropetran and 0.5% flavescens alkali. In the field, 800 times, 1000 times, 1200 times of 2.5% dipropacyclopyrene-matrine compound insecticide, 1000 times, 1500 times, 2000 times of 5% dipropacyclopyrene dispersible liquid, 1% bitter The 800-fold, 1000-fold and 1200-fold ginseng soluble liquids were used as control agents, and a field efficacy test was carried out.

[0049] Specific steps are as follows:

[0050] 1. Test conditions

[0051] The test object is black thorn whitefly [Aleurocanthus spiniferus (Quaintanca)], the test crop is tea tree, and the variety is Pingyang tezao.

[0052] The test site is a young tea garden with dense bud growth. The cultivation conditions (soil type, fertilization, growth stage, row spacing, etc.) and plant growth of all tes...

Embodiment 3

[0077] Mixture Safety Evaluation

[0078] The content of dipropacyclopyrene and matrine in the compound insecticide is lower than or equivalent to the content of commercially available single-dose products, so the safety to humans, animals and crops is in compliance with the standard. The 2.5% dipropterapran-matrine compound insecticide has been classified as a slightly toxic pesticide by the toxicity test results of the accredited institution:

[0079] Rat acute oral toxicity LD50♂>5000mg / kg,♀>5000mg / kg;

[0080] Rat acute dermal toxicity LD50♂>5000mg / kg,♀>5000mg / kg;

[0081] Rabbit eye irritation score is 0 (1h), 0 (1:100) dilution after 48h, no irritation to eyes;

[0082] Rabbit eye irritation score is 0 (4h), non-irritating to the skin.

Abstract

The invention relates to a novel compound insecticide and an application thereof. The compound insecticide comprises the effective components of afidopyropen and a botanical pesticide sophocarpidine, wherein the weight ratio of the afidopyropen to the sophocarpidine is (1:1) to (100:1). The application of the 2.5% afidopyropen.sophocarpidine compound insecticide in the field of agricultural production is discussed, and the compound insecticide has outstanding performance in the aspect of control on insect pests with piercing sucking mouthparts of fruit, vegetable and tea crops. The compound insecticide containing the afidopyropen and the sophocarpidine has the characteristics of being low in dosage, low in toxicity and low in residue, the insecticide resistance is delayed and a foundation is laid for production of high-quality agricultural products.

Description

technical field [0001] The invention relates to a novel compound insecticide, in particular to a compound insecticide for preventing and treating the piercing-sucking mouthpart pests of fruit, vegetable and tea crops. Background technique [0002] The birth of pesticides is a milestone in the history of world agricultural development. The use of pesticides has greatly increased crop yields and effectively solved the problem of food supply. With the long-term and large-scale use of pesticides, the problems of drug resistance, food quality and safety, and ecological environment have become increasingly prominent. In order to improve the control effect of pesticides, farmers often use highly toxic pesticides in violation of regulations, resulting in serious pesticide residues exceeding the standard, which is harmful to human health. significant impact on the ecological environment. Therefore, it is imminent to develop new pesticides with low toxicity, low residue and environme...
