Description
Technical Field
The invention belongs to the technical field of pesticides, and in particular relates to a pesticide fertilizer granule for preventing and controlling crop nematodes and a manufacturing method thereof.
Background
Plant disease source nematodes are harmful organisms which damage crop roots, the damage is severe compared with common diseases, the crop yield is reduced, the quality is reduced, and serious economic losses are caused. Worldwide, nematodes are widely classified as pests that pose serious threats to agriculture. Most nematodes infect crop roots, damage root health, and further cause different degrees of damage to crops. Overground parts often show the phenomena of weak growth vigor, yellowing and wilting of leaves, short plants, malnutrition and the like. These are sometimes not readily noticeable or distinguishable from symptoms caused by other pathogens or adverse factors. According to the statistics of the combined national Food and Agricultural Organization (FAO), the damage of nematodes causes about 12% of food and fiber crops, while the loss of economic crops such as fruits and vegetables exceeds 20%. In the case of very high numbers of nematodes, the nematodes can cause a higher proportion of yield losses, even to be dead. Plant nematodes are estimated to cause agricultural losses over $1,000 billion annually worldwide. In China, the rapid development of protected field facility cultivation provides better environmental conditions for nematode occurrence, and especially the single crop planting mode further increases the damage and the control difficulty of nematodes. Thus, nematodes are considered by many growers to be the most headache problem. Chemical control is an integral part of the integrated management of nematodes in order to control their damage to crops. Over the last decade, there has been a lack of innovative nematicides in the market. The current mainstream products have larger consumption per mu and higher toxicity of the original drugs. In addition, some components are not selective, so that other beneficial organisms can be influenced, soil imbalance is caused, and the problems of increased nematode resistance, environmental pollution, human and animal poisoning and the like can be caused. The pesticide fertilizer which is high-efficiency, low-toxicity, pollution-free, long in lasting period, simple and convenient to use and capable of completing two procedures of killing nematodes and fertilizing by one time is developed by utilizing reasonable pesticide components and fertilizer components, and becomes an effective way for preventing and controlling the nematodes. The invention aims to solve the problems, and provides a pesticide fertilizer, wherein the active ingredients of the pesticide fertilizer are pesticides and fertilizers, so that the pesticide fertilizer can kill nematodes and simultaneously provide nutrients for crops, which promote root growth, promote the rapid healing and growth of root systems damaged by the nematodes, and reduce the damage of the nematodes to the growth and yield of the crops.
Fluopyraclostrobin (fluopyram) belongs to a succinic acid dehydrogenase inhibitor pesticide, has strong nematicide activity, can be used as a nematicide, a bactericide, a seed treatment agent, an agricultural product storage preservative and the like, and achieves the aim of killing bacteria/nematodes by mainly inhibiting a complex of respiratory chains in mitochondria of an energy substance in bacteria/nematodes, losing energy and finally dying. The fluopyram has strong systemic conduction, can be absorbed through roots, stems, leaves and the like and is conducted in plants through phloem, and can be slowly and uniformly distributed on the upper layer in soil. So that the root system can be effectively and long-term protected from pathogen and nematode infection in the rhizosphere range. The fluopyram has a longer lasting period in soil, and can effectively prevent and control various soil diseases and nematodes.
The fluoroolefin sulfone (fluensulfone) belongs to a novel heterocyclic fluorosulfone low-toxicity nematicide, has broad-spectrum and non-fumigating nematicide, has touch-killing activity and systemic conductivity, and is a metabolic inhibitor for the process of obtaining energy storage of plant parasitic nematodes. By contacting the nematodes, the nematodes are inhibited from acquiring lipid energy, the energy reserves of the nematodes are inhibited, and the energy channels acquired by the nematodes are blocked, so that the nematodes are killed. The fluoroolefin linear sulfone has good killing effect on 3 forms of eggs, larvae and adults of nematodes. When acting on eggs, the normal development of larvae in the eggs is disturbed, and the hatchability and the larva development are reduced; when acting on larvae, the utility model causes stiffness and paralysis, weakens the pushing and eating activities of the oral needles, and influences the metabolism and fat accumulation of the larvae.
In order to improve the control effect on nematodes, the invention particularly screens fulvic acid, humic acid, phosphate fertilizer and the like which have promotion effect on the root growth of crops as main fertilizer components, reduces the harm of the nematodes to the crops by promoting the compensation effect of the root growth, simultaneously can finish two procedures of pest killing and fertilizer application at one time, saves labor and time, accords with the rules of crop growth and nematode control, can effectively reduce the control cost of the crop nematodes, and is easy to accept and beneficial to popularization by farmers. The advantages of fluoroolefin linear sulfones are represented by: the novel action mechanism has no interactive resistance with other products; the nematodes are really killed, the irreversibility is realized, and the population quantity is reduced; all worm states acting on nematodes; the use is simple and convenient, and the duration is long; no harm to effective nematodes in soil; low toxicity and is friendly to plants, environment and people.
Phoxim belongs to organophosphorus biocidal insecticide, high-effective low-toxic organophosphorus insecticide, and is characterized by that it uses contact killing and stomach toxicity as main material, and has no internal absorption action, broad insecticidal spectrum and strong knockdown power, so that it is very effective for lepidopteran larva. Because phoxim is unstable to light when applied in the field, the phoxim is fast to decompose and has short lasting period, and the foliar spray has a general lasting period of 2-3 days; however, the medicine is applied into the soil, and the lasting period can reach 1-2 months. Phoxim is suitable for preventing and controlling soil insects, especially grubs of peanut, sweet potato, tomato, vegetable and sugarcane, cutworm, mole cricket, wireworm, root knot nematode and larvae of various lepidoptera pests, and has good effect and certain killing effect on ova.
Avermectin belongs to biological source pesticide, has insecticidal, acaricidal and nematicidal activities, is a high-efficiency broad-spectrum antibiotic insecticidal and acaricidal agent, has the advantages of contact killing, stomach toxicity, strong permeability and no internal absorption effect. The main action mechanism is to interfere the nerve physiological activity and stimulate and release r-aminobutyric acid, and the r-aminobutyric acid has an inhibiting effect on the nerve conduction of arthropods, and the mites become, if mites and insects come into contact with the agent, paralysis symptoms appear, the mites and insects do not take food after being inactive, and the mites die after 2-4 days. The insect is slow to kill because it is not caused to dehydrate rapidly. Although the natural enemies of predatory and parasitic diseases are directly killed, the damage to beneficial insects is small because the residual on the plant surface is small. Has obvious effect on the root of the festival line worm.
In order to improve the control effect on nematodes, the invention particularly screens fulvic acid, humic acid, phosphate fertilizer and the like which have promotion effect on the root growth of crops as main fertilizer components, reduces the harm of the nematodes to the crops by promoting the compensation effect of the root growth, simultaneously can finish two procedures of pest killing and fertilizer application at one time, saves labor and time, accords with the rules of crop growth and nematode control, can effectively reduce the control cost of the crop nematodes, and is easy to accept and beneficial to popularization by farmers.
