Problems solved by technology

At present, the green Lygus has become the main pest on grapes. Both adults and nymphs can eat and cause damage. They use needles to suck the juice of young grape leaves, flowers, young fruits and other young tissues, causing grape leaves to be damaged and missing, and flower buds to fall off. , The fruit is deformed or even falls off, seriously affecting the yield and quality of the grapes, causing serious economic losses
[0003] Lygus green bug has a wide range of hosts, active and easy-flying adults, strong concealment of nymphs, and obvious migration of hosts, which has caused great difficulties in the effective control of this insect. In order to control the damage of this insect to grapes and other crops, Planters have to increase the amount of pesticides used, but long-term use of a large amount of chemical pesticides is likely to cause a series of problems such as excessive pesticide residues in fruits, increased pest resistance, ecological environment damage, and reduction of natural enemy insect species.

Embodiment 1

[0041] Indoor toxicity test and compound ratio screening

[0042] 1.1 Test method

[0043] 1.1.1 Drug preparation

[0044] Component I biogas slurry comes from Shandong Minhe Biotechnology Co., Ltd.; component II uses sulfoxaflor and imidacloprid respectively, and 50% of sulfoxaflor water-dispersible granules come from Dow AgroSciences The company's product; 10% imidacloprid soluble solution is derived from the product of Xingnong Pharmaceutical (China) Co., Ltd.

[0045] 1.1.2 Sources of tested insects and treatment methods

[0046] In this example, the Lygus spp. among Hemiptera pests was selected as the drug efficacy test object. All the tested scorpions were raised indoors for more than 10 generations, and the 3rd instar larvae with the same individual size and lively and healthy were selected as the test insects.

[0047] Test 1 using sulfoxaflor as component II as an example

[0048] Using food impregnation method. The test set a single dose of biogas slurry, a sing...

Embodiment 2

[0062] Field efficacy evaluation test

[0063] The field test set the following treatments: the ratio of biogas slurry and sulfoxaflor was further optimized to 8.89:1, 10.0:1, 14.81:1, 16.67:1, and 4000 times of 50% sulfoxaflor water-dispersible granules, 300 times of biogas slurry was used as the control agent; the ratio of biogas slurry and imidacloprid was further optimized to 4.44:1, 5.0:1, 7.41:1, 8.33:1, and 2000 times of 10% imidacloprid soluble solution and 300 times of biogas slurry were used as the control agent At the same time, a blank control treatment was set up.

[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 Apolygus lucorum, and the test variety is Gernischt vinifera.

[0068] (2) Crop cultivation and environmental conditions

[0069] The test garden was cultivated in hedgerow style, and the tree age was 4 years old, and the occurrence of Lygus lygus over the y...

Embodiment 3

[0108] safety test

[0109] 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:

[0110] Rat acute oral toxicity LD50♂>5000mg / kg,♀>5000mg / kg;

[0111] Rat acute dermal toxicity LD50♂>5000mg / kg,♀>5000mg / kg;

[0112] Rabbit eye irritation score is 0 (1h), 0 (1:100) dilution after 48h, no irritation to eyes;

[0113] Rabbit eye irritation score is 0 (4h), non-irritating to the skin.

[0114] Through a large number of bioassay screenings, the present invention finds biogas slurry and sulfoximine insecticides, phenylpyrazole insecticides, neonicotinoid insecticides, pyridine amide insecticid...

Abstract

The invention belongs to the technical field of compound compositions of insecticides and particularly relates to a compound composition containing biogas slurry and an insecticide and application thereof in crop pest control. The effective components of the compound composition provided by the invention are prepared from a component I and a component II, wherein the component I is biogas slurry;and the component II is one of sulfone imine insecticides, phenylpyrazole insecticides, anabasine insecticides, picolinamide insecticides, pyrethroid insecticides, novel pyridine methylenimine insecticides, benzoyl urea insecticides, antibiotic insecticides and plant source insecticides. The compound composition containing the biogas slurry and the insecticide is applied to control of apolygus lucorum. The compound composition provided by the invention has the advantages of being obvious in synergistic effect, high in drug effect, good in fast-acting property, low in toxicity, low in residue content, long in lasting period, wide in insecticidal spectrum, capable of avoiding and delaying generation of pest drug resistance, convenient to use, safe, reliable and the like.

Description

technical field [0001] The invention belongs to the technical field of pesticide compound compositions, and in particular relates to biogas slurry-pesticide compound compositions and their application in crop pest control. Background technique [0002] The green bug Apolygus lucorum (Meyer-Dür) belongs to Hemiptera Miridae. There are 147 species of host plants in 38 families. and other regions along the Yangtze River Basin. In recent years, with the adjustment of crop planting structure, changes in pest control strategies, and changes in climatic conditions, Lygus lygus has risen from a minor pest to a major pest in my country's agricultural production. The harm is increasing year by year. At present, the green Lygus has become the main pest on grapes. Both adults and nymphs can eat and cause damage. They use needles to suck the juice of young grape leaves, flowers, young fruits and other young tissues, causing grape leaves to be damaged and missing, and flower buds to fall...
