Abstract

The invention discloses an organic fertilizer used as a pesticide to prevent root maggot and an application method thereof. The organic fertilizer used as a pesticide provided by the invention consists of walnut bark and organic fertilizer and can be used as ground fertilizer but also as top dressing. At the beginning of enlargement of garlic bulb (7 to 8 leaves), the rate for inhibiting the root maggot reaches 99.4 percent and reaches 78.2 percent in the harvest, and the output of fresh garlic without being harmed by the root maggot is 491 kg per mu (1 mu is approximately equal to 0.0667 hectares). The organic fertilizer used as the pesticide to prevent root maggot, provided by the invention, has easily-obtained raw materials, simple and convenient application method, no toxicity and pollution, with dual functions of fertilizer retaining and insect expelling, can be used not only for preventing root maggot but also for production of garlic green products and organic products so as to obtain more economic and environmental benefits, thus having popularization value.

Description

technical field [0001] The invention relates to a medicinal organic fertilizer for preventing and controlling root maggots and an application method thereof. Background technique [0002] Root maggots are common names for the larvae of the onion fly Delia antiqua (M.) and the species fly D. platura (M.). They belong to the family Diptera. The two species are mixed. The root maggots that harm garlic are generally dominated by the onion fly. . Garlic root maggots produce 3 generations a year, live through the winter as pupae in the garlic rhizosphere soil, and do serious damage from late April to early May, seriously affecting the yield and quality of garlic. In addition to garlic, root maggots mainly harm lily vegetables such as onions, spring onions, and leeks. At present, the commonly used measures for the prevention and treatment of garlic root maggots at home and abroad include conventional agricultural control, physical control, chemical control and biological control,...
