In recent years, due to the large amount of straw returned to the field, the harm of underground pests has increased year by year, which has become the main limiting factor affecting the growth of wheat seedlings. Doing a good job in the prevention and control of underground pests is the premise of ensuring that the wheat is sown in full seedlings. Commonly used octyl thion, chlorpyrifos and other agents, pests have developed a strong resistance, the control effect is poor. Today, I will introduce you to an excellent formula, which can effectively kill dozens of underground and aboveground pests such as caddisflies, grubs, golden needle worms, ground tigers, garlic maggots, regions, aphids, thrips, brown planthoppers, whitefly and so on, with an effective period of more than 8 months, and completely solve the problem of controlling underground pests.
Recipe Introduction
This formula is chlorpyrifos + thioxamine. Chlorpyrifos is an organophosphorus insecticide, with contact killing and systemic absorption, the residual period on the plant is not long, but the residual period in the soil is long, can control underground pests for a long time, the control effect is significantly better than that of conventional agents such as enemy insects and octyl thiophosphorus, and is an ideal insecticide to replace highly toxic and highly toxic pesticides such as methion and furandan.
Thiamethoxamine is a second-generation neonicotinoid insecticide, which has an assorption and conduction effect, mainly gastric toxicity and touch killing, and can effectively control underground pests such as slugs, ground tigers, grubs, golden needle worms, as well as stinging pests such as aphids, planthoppers and thrips. In addition, it can also promote root growth, increase chlorophyll content, and enhance the resistance of plants to stress, improving yield and quality.
Main role
The two are mixed and used, the synergistic effect is remarkable, with a wide spectrum of insecticide, good quick-activity, long effectiveness, clean and thorough insecticidal, not only for grubs, grubs, golden needle worms, ground tigers, ground maggots, garlic maggots, root knot nematodes, voles and other underground pests have a strong killing effect, but also effectively control aphids, thrips, gray planthoppers, brown planthoppers and other aboveground pests. It also has a good inhibitory effect on pathogens in the soil. Soil permeability is enhanced, seedlings are neat, the root system is developed, the seedlings are robust, the cold resistance is good, the tillering into panicles is high, and the yield is improved and the quality is good. The duration of effectiveness can reach 6 to 8 months.
Scope of application
Chlorpyrifos + thiamethoxamine is a broad-spectrum soil treatment agent that can be used for wheat, sweet potato, peanuts, potatoes, corn, soybeans, ginger, Chinese herbal medicines and other crops, with high safety, good insecticidal effect, long effectiveness, easy to use and other advantages.
How to use
(1) Soil treatment: can be combined with land preparation fertilization, 15% chlorpyrifos granules per mu 1 ~ 2 kg + 1% thioxasteramine granules 2 kg + fully decomposed organic fertilizer 50 kg, mixed evenly after spreading, and then land preparation, you can achieve the purpose of killing underground pests, effectively prevent pests from harming seedlings.
(2) Seed fertilizer sowing: When sowing wheat, use 0.1% chlorpyrifos amine granules of 0.1% per mu + 15 kg of wheat seeds, and sow the seeds together after mixing the agent and seeds, and evenly distribute around the seedlings after the agent is dissolved, effectively protecting the seedlings from pests.
