Biological-type composite pesticide for liriomyza

Abstract

The invention discloses a biological-type composite pesticide for liriomyza. The biological-type composite pesticide for the liriomyza is prepared from, by weight, 5%-10% of unboiled oil, 2%-5% of bitter chrysanthemum elements, 2%-5% of matrine and the balance beauveria bassiana liquid, and the total amount is 100%; the beauveria bassiana liquid is prepared from, by weight, 4% of brown sugar, 2% of soybean cakes, 0.05% of zinc sulfate, 0.05% of magnesium sulfate, 0.01% of manganese sulfate, 0.003% of ferrous sulfate and the balance water to achieve the total amount of 100% and inoculated with 0.1% beauveria bassiana. According to the biological-type composite pesticide for the liriomyza, the liriomyza can be effectively prevented from harming crops, and the effects of triggering the crops to generate self-protection, promoting strong growth of the crops nd improving the quality of the crops are achieved.

Description

technical field [0001] The invention relates to a biotype combination medicament of Liriomyza sativae and belongs to the technical field of plant pest control. Background technique [0002] Liriomyza sativae belongs to Diptera Liriodidae. It mainly harms more than 110 kinds of plants in 22 families, such as cucumber, tomato, eggplant, cowpea, broad bean, soybean, watermelon, wax gourd, loofah, etc. Its larvae and adults can be harmful. The leaves of the plant are stabbed for feeding and egg laying. The larvae sneak into the leaves and petioles to cause damage, forming irregular serpentine white worm tracks. The damaged leaves are severely covered with latent marks, resulting in yellowing, chlorosis, and scorching of the leaves. When the chlorophyll is destroyed, photosynthesis is affected, and the leaves of the injured plants fall off. , The fruit is burnt, causing dead seedlings and ruined seedlings in severe cases. The current prevention and control methods include biolog...

Problems solved by technology

The larvae sneak into the leaves and petioles to cause damage, forming irregular serpentine white worm tracks. The damaged leaves are severely covered with latent marks, resulting in yellowing, chlorosis, and scorching of the leaves. When the chlorophyll is destroyed, photosynthesis is affected, and the leaves of the injured plants fall off. , The fruit is burnt, causing dead seedlings and ruined seedlings in severe cases. The current prevention and control methods include biological control, using natural enemies that release Liriomyza spp. Parasitic control, biological control is affected by the environment and the time of application, resulting in poor control effect; physical control methods can be used to stick yellow boards to reduce insect clusters. Due to the weak flying ability of Liriomyza sativae, insect traps are only suitable for pupae Adults are effective, but the control effect is poor. Farmers usually choose chemical pesticides for control. Common chemical pesticides are organophosphorus, phenylpyrazoles, and triazines (insect growth regulators) chemical synthetic agents, such as chlorpyrifos and abadine. , nicotine EC, fipronil, and cyromazine for prevention and control. The microbial metabolites include abamectin. In actual use, it is found that resistance to abamectin occurs. How to use the physiological characteristics of Liriomyza sativae, Organizational structure, the use of plant sources, biological sources and trace elements to formulate an environmentally harmonious, non-toxic and non-residual, efficient and rapid control of root-knot nematodes is an important and urgent need for breakthroughs that plant protection technicians need to study in depth. technical challenge
