West melon mantle control
Guadixia is a larva of a melon seed fly, also known as a melon rootworm, and is one of the melon pests. The melon carp is 6-7 mm long, with a slightly yellowish white color and resembles feces. It feeds on the roots of western melon and causes death withered. In the conditions of high temperature and humidity or the application of unfamiliar plots of soil fertilizer and cake fertilizer, it is most prone to happen, which will seriously affect the production of western melon. The mantle mainly harms the root of the melon, and the watermelon also harms the site of pressure control, resulting in the gradual loss of water and withering. The larvae eat the roots of the western melon. In severe cases, the root epidermis is completely empty, causing the crops to wither due to lack of water, causing the roots to decay until they die. Its performance symptoms are similar to those of wilt disease. Some melon farmers are controlled by wilt disease and delay the period of prevention and treatment. The prevention and control of the mantle should start from the whole of the agro-ecosystem. According to the relationship between the fly and the cultivation environment, comprehensive utilization of various measures should be made to reduce the reproduction rate and the survival rate of the pest population as much as possible so as to control the population of the mantle to cause crops. Below the level of economic loss. First, the agricultural control of fly species tends to produce raw manure, so do not use raw manure as a fertilizer, even if the use of fully cooked organic fertilizer, but also pay attention to deep application, if necessary, mixed manure in the manure to prevent the species fly in the Manure lays eggs. Second, chemical control in the peak period of adult egg laying and larval hatching in a timely manner poisoning is the key to drug control. 1. Kill the adult worms and then spray them with 3000-fold 2.5% deltamethrin or 90% dipterex crystals 1000 times for the adult insects, once every 7 days, and apply them 2 or 3 times. 2. Drugs kill larvae, field plots that have taken place, can be used 40% phoxim EC 1000 times or 40% chlorpyrifos 1000 times leaching 2 or 3 times, the best evening administration, once every 7 days.
