Ginger and ginger, ginger Zingiberaceae, is the perennial herbaceous plants, is an important one of specialty vegetables in our city, perennial planting 50 thousand acres. The production process of the main disease of ginger: ginger wilt, root knot nematode, flocks of Pythium soft rot disease. The main pests of ginger borer. The storage period is alien pest odoriphaga. Only the reasonable and effective prevention and control of plant diseases and insect pests can increase the yield and quality of the unit area, so that the plant can obtain more economic benefits.

1, ginger blast, bacterial disease, is a devastating disease commonly occurred in the production. Prevention and cure method: (1) soil disinfection. According to 25-35 kg per mu of chloropicrin fumigation of soil. The use of specific methods: 30 days before sowing, spraying with special tools according to the distance of about 30 cm, liquid will be applied into the whole good 15-25 cm deep soil layer, each point injected 2-3 ml, then covered with plastic film for 3-5 days, 15-20 days after removal of film preparation. Chloropicrin highly toxic, must be operated by professional personnel when applying pesticide. In addition, lime nitrogen can be used for soil treatment. (2) agricultural prevention and control. Strict selection of disease-free ginger, rotation of crops, fertilizer application net, pouring water, combined with fine management, control of ginger blast has significant effect. (3) were found to eradicate. When the field strain found, should be timely removal of diseased center, will be around 0.5 meters with healthy plants removed, and digging in infected soil, disease point looking lime, and then buried in sterile soil clean.

2, root knot nematode disease also known as laipi disease, scabies skin disease, the disease is the pathogen of Meloidogyne incognita, is the main disease occurred in recent years. Control method: the root knot nematode disease pathogens in the soil in a wide range of distribution, long period of onset, prevention and treatment are more difficult. Available soil can also use chloropicrin fumigation, nematicidal isopropyl ether 3 kg (available soil fumigation). If it is found that the growth process of nematodes, available 1.8% abamectin 2000 times Guangen, Meixue irrigation medicine 100-150 grams, after irrigation water.

3, the knot group of rotten mold soft rot, also known as root rot, soft rot. Prevention methods: prevention strategies and measures are the same with ginger blast, emphasize prevention, comprehensive prevention and control. To do a good job in the selection of health, kind of ginger disinfection, the implementation of rotation and improved cultivation techniques and other links. Because of the disease caused by the fungus by Pythium spp., to use of fungicides, 50% metalaxyl wettable powder 800-100 times or 64% oxadixyl mancozeb wettable powder 500 times liquid, 50% Rui toxic copper wettable powder 500 times liquid, 72% DuPont rook WP 1000 times liquid 60%, Rui Al Cu WP 800 times guangen.
