Disease control Ginger diseases mainly include ginger borer, anthrax, and echinoderms. The most serious threat to ginger production is ginger borer disease. The prevention and control of ginger borer should be based on agricultural control, supplemented by chemical control, and cut off the transmission route. 1 The incidence of land plots must be separated by more than 3 years before replanting. Can rotate with food crops, onions, garlic, etc., but can not be rotated with the Solanaceae crop. 2 Select from a disease-free ginger field, harvest and storage separately; ginger cellars are disinfected in time; before germination, soak in a “root Yekang†80 to 120 times liquid. 3 Jiang Tian should choose high-desert, well-drained plots. From high ridges, drains are provided. 4 The organic fertilizer to be used must be fully decomposed, and ginger and garlic can be used as a “strong root agentâ€; irrigation is done with non-polluted well water, and the diseased plant is strictly prohibited from contaminating well water. 5 The diseased plants were found to be eradicated in time, lime was applied in the diseased holes, filled with sterile soil, and the diseased bodies were deeply buried. 6 Based on the time of onset in previous years, 50% sterilized Weiwei 1000 times before the onset of disease to irrigate the roots, 0.5 kg of each irrigation liquid, irrigation once every 7 to 10 days, and even irrigation 3 to 5 times. 7 Ginger rickets mainly invade from wounds. To reduce the chance of disease, do not dig ginger seeds. Timely control of underground pests. The prevention and control of other diseases are similar to the control of Jiangyan disease. In addition to agricultural control, 64% “Pusha†WP can be used at the initial stage of disease, and “Gourd Poultry†is added, and sprayed once every 7 to 10 days. ~ 5 times, this will not only prevent disease but also increase ginger production and quality. Insect pest control Ginger pests are mainly ginger aphids, beet armyworm and underground pests. 1 Spodoptera exigua. The insect's epidermis is thick and smooth, pesticides are not easy to infiltrate, and the general pesticide control effect is poor. It can spray 20% of rice full of plastic suspension 1000 to 1500 times liquid, 7 to 10 days to spray 1, and even spray 2 to 3 times. 2 ginger aphids. Ginger worms are the heartworms that ordinary people say. Do not shave with corn stalks to reduce the source of insects. Gingers should be cleared of broken plants and weeds and burned. It is necessary to pay attention to the timing of prevention and control. It should be sprayed once every 3 to 5 days in mid-June on 40% of 1000-2000 times of insecticidal king emulsion oil, and spray 3 to 5 times. Pay attention to the back of the blade when spraying. Spray it. Or inject the liquid into the insect mouth of the victim plant. 3 Underground pests. When ginger is sown, 5% of phoxim is sprinkled into the sowing ditch, and 2 to 3 kg of medicine is applied per 667 square meters.
