Problems solved by technology

The three kinds of pest mites all cluster on the back of the leaves to suck the juice with their active mites. When the damage is severe, the leaves often fall off early, which seriously weakens the tree vigor and affects the yield and quality of fruit trees.
And no one has reported on the insecticidal composition and application of biogas slurry and acaricide compound

Embodiment 1

[0039] Indoor toxicity test and compound ratio screening

[0040] 1.1 Test method

[0041] 1.1.1 Drug preparation

[0042] Component I biogas slurry comes from Shandong Minhe Biotechnology Co., Ltd.; component II uses pyridaben and spirofen respectively, and 20% of pyridaben wettable powder comes from Dongsheng United Pesticide Industry Co., Ltd.; The 240 g / L spirodiclofen suspension concentrate comes from Bayer Crop Science (China) Co., Ltd.

[0043] 1.1.2 Sources of tested insects and treatment methods

[0044] Test 1 used pyridaben as component II as an example.

[0045] Panonychus apples were collected from the experimental farm of Yantai Academy of Agricultural Sciences.

[0046] For indoor toxicity determination, refer to the Slide-dip method recommended by FAO (Food and Agriculture Organization of the United Nations). Cut the double-sided tape into 2-3cm long, stick it on one end of the microscope slide, and use tweezers to peel off the glue. Pick out adult mites w...

Embodiment 2

[0062] Field efficacy evaluation test

[0063] The following treatments were set in the field test: the ratio of biogas slurry and pyridaben was further optimized to 6.7:1, 7.5:1, 11.1:1, and 12.5:1, with 20% pyridaben WP 3000 times and biogas slurry 300 times as the Control agent; the ratio of biogas slurry and spirodiclofen was further optimized to 11.1:1, 12.5:1, 18.5:1, and 20.8:1, with 240 g / liter spirodiclofen SC 5000 times and biogas slurry 300 times as the control agent , while a blank control treatment was set.

[0064] 2.1 Test method

[0065] 2.1.1 Test conditions

[0066] (1) Selection of test objects, crops and varieties

[0067] The test object is Panonychus spp., and the test species is Red Fuji.

[0068] (2) Crop cultivation and environmental conditions

[0069] The test was carried out on May 19, 2017 at the Experimental Farm of the Academy of Agricultural Sciences in Yantai City, Shandong Province. The apple trees were 12 years old, and the occurrence of...

Embodiment 3

[0105] safety test

[0106] The content of pesticides in the compound composition is 10% to 20% lower than that of commercially available products, and the single agent of biogas slurry has no pollution and no residue, so the toxicity of the compound composition to humans and animals and the safety to crops meet the requirements of. The results of the toxicity test of the accredited institution show that the compound insecticide belongs to the slightly toxic pesticide:

[0107] Rat acute oral toxicity LD50♂>5000mg / kg,♀>5000mg / kg;

[0108] Rat acute dermal toxicity LD50♂>5000mg / kg,♀>5000mg / kg;

[0109] Rabbit eye irritation score is 0 (1h), 0 (1:100) dilution after 48h, no irritation to eyes;

[0110] Rabbit eye irritation score is 0 (4h), non-irritating to the skin.

[0111] The present invention discovers biogas slurry and heterocyclic acaricides, tetronic acid acaricides, novel benzoylacetonitrile acaricides, novel acrylonitrile acaricides, and novel oxazole contact acar...

Abstract

The invention belongs to the technical field of complex compositions of insecticides, particularly relates to a complex composition containing biogas slurry and acaricide and application thereof. Thecomplex composition comprises active ingredients of an ingredient I and an ingredient II, wherein the ingredient I is the biogas slurry; the ingredient II is selected from one of heterocycle acaricides, tetronic acid acaricides, novel benzoylacetonitrile acaricides, novel acrylonitrile acaricides, novel oxazole touch killing type acaricides, pyrazole amide acaricides, bifenazate acaricides, antibiotic acaricides, organic tin acaricides, tetrazine acaricides, thiazolidone acaricides, sulfite acaricides, novel thiourea acaricides and pyrethroid acaricides. The complex composition has the advantages that the environment compatibility is realized; the performance of high efficiency and low toxicity are realized; the prevention and control effects on mite pests are obvious.

Description

technical field [0001] The invention belongs to the technical field of compound compositions of insecticides, and in particular relates to a compound composition containing biogas slurry and acaricides and its application. Background technique [0002] Apple panonychus ulmi Koch and hawthorn spider mite (Tetranychus viennensis Zacher) are the main pests of deciduous fruit trees in northern my country, and Tetranychus urticae Koch is a worldwide pest. The harm of spider mites has surpassed Tetranychus hawthorne and Panonychus apples, and has become the most harmful mite to fruit trees. The three kinds of pest mites all clustered on the back of the leaves to suck the sap with their active mites. Severe damage often caused the leaves to fall off early, seriously weakening the tree vigor, and affecting the yield and quality of fruit trees. At present, the control of these three kinds of harmful mites is still dominated by chemical control. Due to the extensive use of acaricides ...
