Description
Technical Field
The invention belongs to the technical field of pesticides, and particularly relates to a compound seed coating agent.
Background
The peanut is one of four major oil crops in China, the yield position is the first global, the peanut is one of foreign exchange crop varieties in the net export of China, the planting area is rapidly enlarged in recent years, and the peanut is influenced by factors such as climate, variety and cultivation management mode. The peanut rot is also called as rotten fruit disease of peanuts, and the disease is more serious in the years of more rainwater in the podding period of land blocks planted in continuous cropping for many years. According to investigation, the yield of the affected land is reduced by 20% if the affected land is light, and the yield is reduced by more than 50% if the affected land is serious. The disease becomes a main disease in peanut production, and extremely serious threat is formed to the yield and the quality of peanuts. In production, the diseases are common, the prevention difficulty is high, the comprehensive prevention and control are realized in a mode of combining multiple modes, the yield and the quality are improved, and the planting benefit is further improved. The rot disease of peanut is mainly manifested in that the peanut is rotten, the light half of the pod is brown or black, the kernel inside is small and hard, the development is poor, the peel is yellow, the serious whole pod is dark black, the peel and the kernel are rotten, and the rot disease generally occurs in the whole plant or in the form of a piece. The peanut can be attacked from the pod producing period of 7 months to the harvesting period. The peanut rot is caused by various reasons, especially fusarium fungal soil-borne disease bacteria, and is caused by soil lack of calcium and soil bite or infection of underground insects such as grubs and the like.
The zhongshengmycin has excellent preventing and treating effect on rice blast and no influence on rice seedling stage. When preventing and treating rice blast and chestnut blast, the concentration is 40r, for example, 6000r/g wettable powder is used, 75kg of water is added into every 50g of medicinal powder, about 1 mu of water is sprayed, when the leaf blast reaches grade 2, the pesticide is sprayed once again about 7 days after the first pesticide application when the disease condition is serious, the pesticide is sprayed when the ear blast of panicle neck is about one third of the ear of rice field, and when the ear neck blast is serious, the pesticide is sprayed once in the full panicle period except for the broken-open period. The 0.4% powder can be directly sprayed with powder for application, with a dosage of 1.5kg per mu, preferably applied in the presence of dew in the morning and evening, so that the powder can be applied on rice plants. In the found experiments, the zhongshengmycin has special effects on controlling 20 ml of one kettle of water for controlling tomato leaf mold, bacterial angular leaf spot of watermelon, peach gummosis, scab, perforation and other diseases.
The new triazole fungicide of ipconazole has the following product properties: the ipconazole is an ergosterol biosynthesis inhibitor and has functions of systemic absorption, protection and treatment. Tests prove that the ipconazole is safe to crops. Applicable crops and control objects: can be used in the fields of paddy rice, grain, ornamental plants, non-crop plants and the like to prevent and treat a plurality of seed diseases; especially effective for rice bakanae disease, leaf spot disease, rice blast and the like; and can effectively prevent and control stem base rot, head smut and the like in the corn seedling stage. Other countries use the conditions: in the united states, ipconazole is used as a seed treatment fungicide for many crops; in Japan, ipconazole has been used for rice for a long time to control damping-off and the like. The two isomers of ipconazole are equally effective. Many varieties of triazole bactericides are used as seed treatment agents, and the triazole bactericides have high activity and are easy to cause phytotoxicity. But the activity of the ipconazole is higher but the safety is better for the current market products. Although the ipconazole belongs to patent overdue products, domestic enterprises do not register the ipconazole products except for split-package registration, and the market prospect is promising.
Clothianidin is an insecticide in neonicotinoids, is a novel efficient, safe and high-selectivity insecticide, has similar action to nicotinic acetylcholine receptors, and has contact poisoning, stomach toxicity and systemic activity. The pesticide is mainly used for preventing and controlling hemiptera, coleopteran, dipteran and certain lepidopteran pests such as aphids, leafhoppers, thrips, plant hoppers and the like on rice, vegetables, fruit trees and other crops, has the advantages of high efficiency, broad spectrum, low dosage, low toxicity, long efficacy duration, no phytotoxicity to the crops, safe use, no cross resistance with conventional pesticides and the like, has excellent systemic and osmotic effects, and is another variety for replacing high-toxicity organophosphorus pesticides. The pesticide has novel and special structure and more excellent performance compared with the traditional nicotine pesticide, and is likely to become a worldwide large-scale pesticide variety.
The pesticide in the prior art has the disadvantages of not ideal effect for preventing and treating fruit rot and bacterial wilt, large dosage and easy environmental pollution, so further improvement is needed.
