Grubs and garlic maggots are the most important underground pests in garlic fields. Because they are lurking in the soil, they are not only difficult to find, but also difficult to control. Every year, there are a large number of plots. Due to the harm of these underground pests, production is reduced.Highly toxic pesticides such as chlorpyrifos and phoxim have been banned. What kind of pesticide can be used to achieve the desired control effect?Today, I would like to introduce a broad-spectrum, high-efficiency, low-toxicity, and low-residue insecticide to prevent and control underground pests in garlic fields. The effective period can reach more than 120 days, and the longest can reach 210 days. This agent is clothianidin granules.
1.What type pesticide is clothianidin?
Clothianidin is a second-generation neonicotinoid insecticide developed in the 1990s. It mainly acts on the acetylcholine receptors in the pests. After acting on the pests, it will make the pests extremely excited, and then the whole body will convulse, paralyze and die. It mainly has contact and stomach poisoning effects, and has strong systemic conductivity. It can not only effectively kill aphids, thrips, planthoppers, whiteflies and other piercing-sucking pests, but also kill golden needle insects and garlic maggots. , underground pests such as grubs, mole crickets, etc., have slow metabolism in plants, have a long lasting effect, good insecticidal effect, and have no cross-resistance with insecticides such as phoxim, imidacloprid, chlorpyrifos, acetamiprid, and pyrethroids. Low toxicity, it is the best choice to replace highly toxic organophosphorus pesticides.
2、Main advantage
(1) Wide range of insecticidal effects: Clothianidin can not only effectively kill underground pests such as grubs, golden needle insects, garlic maggots, cutworms, etc. in the soil, but also treat aphids, planthoppers, thrips and other aboveground pests.
(2) Low toxicity and low residue: Clothianidin LD50>5000 mg/kg, which is a low toxicity product; low toxicity to humans and animals, safe for beneficial organisms. It has little impact on the environment and is the first choice for the production of pollution-free agricultural products.
(3) Easy to use: Clothianidin granules are produced by the production process of slow-release fertilizer, using special additives and fillers, no dust, uniform particle size, can be manually or mechanically spread, easy to operate and use Convenient, labor-saving and labor-saving.
(4) Long lasting effect: Clothianidin has a strong systemic conduction effect, and has both stomach poisoning and contact killing effects. It can quickly reach around the root system in the soil. After being absorbed by the root system, it can be quickly transmitted to various parts of the plant to kill the pests. Clothianidin is slowly metabolized in the plant and is not easy to decompose. It has a long lasting period. At one time, the entire crop growth period can be basically controlled from pest damage.
(5) Significant growth promotion: clothianidin can stimulate the growth of plant roots while protecting crop roots from pests, and has the effect of promoting root growth of crops such as garlic. It can also increase chlorophyll content in leaves, enhance photosynthesis, and improve crop yield.
3.Usage method
Before sowing garlic, use 2-4KGS of 1% clothianidin granules per mu, add 30-50 kilograms of fully decomposed organic fertilizer, mix evenly, combine with soil preparation, spread evenly on the soil surface, and then level and rake finely. , and then sow, clothianidin granules dissolve slowly in the soil when encountering water, and distribute the agent evenly around the root system of the seedling. After being absorbed by the root system, it can be quickly transferred to the aerial part of the garlic seedling, which can not only kill the grubs in the soil It can also effectively protect the seedlings from being harmed by garlic maggots, and the duration of validity can reach 120 to 210 days, which can basically control the whole garlic growth period from being harmed by pests.
