Coated insecticide-fertilizer for preventing diseases and insect pests of strawberry and preparation method thereof

Abstract

The invention discloses a coated insecticide-fertilizer for preventing diseases and insect pests of strawberry. The coated insecticide-fertilizer is characterized by being prepared from the following raw materials in parts by weight: 10-14 parts of peanut meal, 12-15 parts of seaweed meal, 13-16 parts of soybean meal, 9-11 parts of zeolite powder, 14-19 parts of urea, 14-18 parts of potassium double superphosphate, 1-2 parts of zinc sulfate, 15-18 parts of hydroxypropyl methylcellulose, 2-4 parts of fumaric acid, 1-2 parts of sodium tetraborate, 6-8 parts of BSFA, 5-7 parts of EM microbial inoculum, 10-15 parts of soil improvement agents and a right amount of water. By utilizing nutrient elements which meet the requirement for crop growth and the natural antibacterial and insecticidal effects of sweet potato seeds and thick-fruited millettia seeds, the coated insecticide-fertilizer disclosed by the invention not only can be used as an insecticide, but also can be used as a fertilizer and is capable of loosening the soil, enhancing the permeability of the soil and improving the physical property of the soil, thereby greatly increasing the additional value of products; and the added BSFA plays roles in loosening the soil, enhancing the fertilizer retaining capacity of the soil, strengthening the adhesive power and absorbing capacity of strawberry root systems. The coated insecticide-fertilizer disclosed by the invention has the advantages of easiness and convenience in processing, low cost and easiness in operation, is safe to the environment and can reduce the labor output and increase the output value.

Botrytis cinerea is the main disease of strawberry, which mainly harms flowers and fruits. Botrytis cinerea will soften, rot, and lose aroma and flavor of fruits, directly affecting the yield and quality of fruits; powdery mildew is also one of the main diseases, which mainly harms leaves , can also attack petioles, flowers, fruit stems and fruits. Once infected with this disease, the leaf margins will shrink and scorch. When the fruits are damaged in the early stage, the young fruits will stop developing, lose luster, harden and dry, which seriously affects the quality of berries; leaf spot The disease mainly harms the leaves, seriously affects the photosynthesis of the leaves, and weakens the cold resistance and disease resistance of the plants; the red spider is small in size, and only a small red spot can be seen with the naked eye. It reproduces multiple generations a year, with strong fecundity, and The overlap of generations increases the difficulty of prevention and control. It generally sucks the juice of young leaves, which will damage the tissue and chlorophyll, retard the growth of leaves, and seriously affect the yield; Because the nectar excreted by aphids pollutes leaves and fruits, and it has strong reproductive ability and is also a medium for spreading viruses, so once strawberries are infected, the consequences will be disastrous
