technical field

The invention belongs to the technical field of compound compositions of pesticides, and in particular relates to a compound composition containing biogas slurry and pesticides and its application.

Background technique

Apple yellow aphid (Aphis citricola van der Goot.) is one of the main pests that occur on apple trees in northern my country. Adult aphids and nymphs gather to harm young buds, young branch tops and young leaves. The tip of the leaf rolls horizontally or bends downward to the back of the leaf. When it occurs seriously, it can cause early leaf fall and tree vigor weakening, which has a great impact on the yield and quality of apples. At present, the control of apple yellow aphid in my country is still dominated by chemical control, but the long-term unreasonable large amount of chemical pesticides has led to problems such as increased control costs, excessive fruit residues, environmental pollution, and the development of drug resistance. The public's close attention to food safety and the increasing call for global environmental protection require researchers to find effective and safe control methods. Therefore, the development and utilization of pesticide resources that are compatible with the environment and harmless to humans are increasingly sought by various countries. of favor.

In the actual process of agricultural production, a large number of single-use chemical insecticides have been abused for a long time, which has led to the continuous strengthening of the resistance of the apple yellow aphid and the increase of pesticide residues. The compounding of ingredients from different varieties is a very common way to control resistant pests. After research by the inventor, it has been found that there is no report on the compounding of biogas slurry, especially chicken manure biogas slurry and insecticides, for the control of apple yellow aphid.

Detailed ways

In order to make the purpose, technical scheme and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with laboratory test measurements, field drug efficacy test, and safety performance test.

The active ingredients of the compound composition provided by the present invention include component I and component II, the component I is biogas slurry, and the component II is pyridine amide insecticides, sulfoximine insecticides, new One of picolimine insecticides, neonicotinoid insecticides, pyrethroid insecticides, and botanical insecticides, the properties of the selected materials for component I and component II are introduced as follows.

Biogas slurry (bigoas slurry) is the residue after anaerobic fermentation of various organic matter such as human and animal manure and crop straw. It has comprehensive nutrients and is rich in humus and other organic substances. It is a quick-acting organic compound fertilizer. Biogas slurry not only has a significant effect on improving the yield and quality of fruits and vegetables, but also has a significant inhibitory effect on many plant pests and pathogenic fungi. In this study, the biogas slurry was obtained from chicken manure through the A&T biological fermentation process and the cutting-edge U-NRO physical multi-stage purification technology.

The representative product of pyridine amide insect growth regulator is flonicamid (flonicamid), which is a new type of insecticide developed by Ishihara Sangyo Corporation (ISK) in Japan. The chemical name (IUPAC) is N-cyanomethyl-4-(trifluoromethyl ) nicotinamide, which has contact and stomach poisoning effects, and also has good nerve agents and rapid antifeedant effects, can be used in fruit trees, grains, potatoes, rice, cotton, vegetables, beans, cucumbers, eggplants, melons, tea trees and ornamental plants, etc. , Control piercing-sucking mouthparts pests, such as aphids, whiteflies, brown planthoppers, thrips and leafhoppers, among which it has excellent control effect on aphids. Aphids and other piercing-sucking mouthparts will be quickly prevented from sucking the juice after inhaling the plant juice with flonicamid. There will be no excrement at all within 1 hour, and eventually they will die of starvation.

Neonicotinoid insecticides, as agonists of nicotinic acetylcholine receptors on the post-synaptic membrane of insect nerves, have good root systemic, gastric toxicity and contact killing effects, and are effective in controlling apple yellow aphid, green peach aphid and cotton aphid. The main agent for pests such as planthoppers and planthoppers. The neonicotinoid insecticides currently on the market mainly include imidacloprid, thiamethoxam, clothianidin, thiacloprid, dinotefuran, acetamiprid, and nitenpyrid. Amine (nitenpyram), chlorothialine (imidaclothiz) and sulfoxaflor (sulfoxaflor), etc.

Sulfoxaflor (sulfoxaflor) is a representative product of sulfoximine insecticides, developed by Dow AgroSciences of the United States. This type of insecticide acts on a unique binding site in the nicotinic acetylcholine receptor (nAChR) Points, can effectively control aphids, whitefly and stinkbugs and other piercing-sucking mouthparts pests.

Pyrethroids are a class of broad-spectrum insecticides emerging after organochlorine, organophosphorus and carbamate pesticides. Due to their high efficiency, low toxicity, low residue and easy degradation, they have been widely used in agriculture. Prevention and control of pests, sanitation pests and grain storage pests. Pyrethroid insecticides mainly act on insect voltage-gated sodium channel (voltage-gated sodium channel, VGSC), affecting its activation and inactivation kinetics, thus causing the conduction disorder of nerve excitability. Pyrethroid insecticides currently on the market mainly include cyhalothrin, deltamethrin, and cypermethrin.

In 1988, the Swiss Syngenta Company developed a new type of pyridyl imine insecticide - pymetrozine (pymetrozine), the chemical name is (E)-4,5-dihydro-6-methyl-4-( 3-pyridylmethyleneamino)-1,2,4-triazin-3(2H)-one [1]. Due to the unique mode of action of this type of insecticide, high efficiency and low toxicity, and environmental and ecological safety, it is very suitable for the resistance management and comprehensive control of piercing-sucking mouthparts pests. It is used for deciduous fruit trees, vegetables, potatoes, ornamental plants, Cotton, citrus, tobacco and other crops control aphids, whiteflies, and planthoppers, and are effective for both larvae and adults.

Plant-derived insecticides use plant secondary metabolites as the main active ingredients, and have the advantages of easy degradation, low toxicity, and certain selectivity to natural enemies. They have become ideal agents to replace chemical pesticides to control crop pests. Veratrine, azadirachtin, matrine, rotenone, picroderm, pyrethrins, osthole, nicotine, etc. are some of the more common plant-derived insecticides in production.

Taking the prevention and control of apple yellow aphid as an example, the present invention compounded the biogas slurry with various insecticides, and screened out the best ratio of the compound insecticides through indoor and outdoor tests, with remarkable synergies and reduced chemical The amount of pesticides used in the field is conducive to reducing environmental pollution and controlling the occurrence and development of pest resistance.

For each treatment of 10 apple branches collected from the field, use a small brush to remove winged adult aphids on the apple leaves, remove nymphs, and keep the same individual, healthy and lively wingless adult aphids. , absorb the excess medicinal liquid, investigate the base number of aphids, then insert the branches into glass bottles with water, and check the number of living aphids on the branches after 48 hours. Those that crawl normally are living insects, and other individuals (cannot crawl, roll over or completely die, etc.) belong to dead insects. Find aphid mortality and corrected mortality.

Mortality = number of dead insects/number of initial insects*100

Adjusted mortality = (treatment mortality - control mortality) / (100 - control mortality) * 100
