Embodiment 1

[0015] Example 1: Indoor Toxicity Test of Pyriproxyfen and Spinosyn on Thrips

[0016] The test uses thrips as the test object, and the specific method is as follows:

[0017] (1) Test agents and test insects:

[0018] 95% pyriproxyfen technical (Shanghai Shengnong Biochemical Products Co., Ltd.);

[0019] 90% spinosad technical (Dow AgroSciences);

[0020] The original drug was prepared into the required test drug according to the conventional method.

[0021] Flower thrips (Frankliniella intonsa): The test insects were collected from Sanya, Hainan.

[0022] (2) Test method:

[0023] Thrips flower: The test method refers to "People's Republic of China Agricultural Industry Standard NY / T1154.7-2006" and "People's Republic of China Agricultural Industry Standard NY / T1154.14-2008". The test method adopts leaf soaking method. Use a cowpea leaf dish with a diameter of 1 cm to soak in a series of concentrated medicinal solutions for 5 seconds, take it out and dry it, and put ...

Embodiment 2

[0050] Example 2: Research on the Resistance of Pyriproxyfen and Spinosyn and Their Compounds

[0051] The source of the test original drug: 95% pyriproxyfen original drug (Shanghai Shengnong Biochemical Products Co., Ltd.); 90% spinosad original drug (Dow AgroSciences, USA); the original drug was prepared into the required test drug according to the conventional method .

[0052] Flower thrips (Frankliniella intonsa): The test insects were collected from flower thrips on beans in Yangcun, Boluo County, Guangdong.

[0053] Indoor toxicity test of the test agent was carried out by immersion method, and population pressure was selected by spray method. The medicaments and doses used are as shown in Table 2. Use a hand-held sprayer to spray the carob seedlings with the thrips population. The concentration of the drug solution is 50%-80% of the lethal dose of thrips. The remaining worms continue to be subcultured with seedlings indoors, and so on. Treat 20 generations of test in...

Embodiment 3

[0059] Example Three: Preparation of 5% Spinosyn Pyriproxyfen EC

[0060] Take by weighing 2.63 grams of 95% pyriproxyfen former drug, 2.78 grams of 90% spinosad former drug, 5.5 grams of calcium dodecylbenzenesulfonate, 3.5 grams of octylphenol polyoxyethylene ether, supplemented with methyl esterified soybean oil Total weight up to 100 grams. Put the above components into a mixing tank according to the conventional method for preparing cream, mix, and stir evenly to form a preparation 5% spinosad · pyriproxyfen EC (the mass ratio of spinosad and pyriproxyfen is 1:1).

Abstract

The invention relates to a pyriproxyfen-containing insecticide composition and application thereof. The active ingredients of the composition are pyriproxyfen and pleocidin. The pesticide composition of the invention can produce obvious synergetic effect for preventing and curing agricultural insects and sanitary insects, particularly for preventing and curing thrips. When the composition is used in field, the dosage in field, environmental pollution, pesticide residue and the developing speed of disease resistance in insects are reduced.

Description

technical field [0001] The invention relates to a pesticide composition and application thereof. The active ingredients of the composition include pyriproxyfen and spinosyn. Background technique [0002] Thrips is a pest of the order Thysanoptera, which has a large reproduction rate and obvious overlapping generations. It is commonly found in melons, legumes, vegetables and fruit trees. It has the characteristics of high population density, small body size, and easy outbreak. It mainly harms tender flowers, young shoots and small fruits, and can cause serious losses, with a loss rate of up to 10%-50%. In recent years, it has become a major pest in Hainan melon and bean planting areas; Guangdong fruit areas, flowers and other planting areas. The main control chemicals such as imidacloprid, acetamiprid, etc. used alone cannot effectively control the pest. [0003] The development of new pesticide varieties is far behind the development of thrips resistance. In this way, th...
