Growing Techniques 0 views
Soybean root maggot, also called soybean root miner fly. It only harms soybean and wild soybean. The larvae bite and feed on the roots of soybean seedlings, forming maggot tunnels and excreting frass, causing root rot and stunted soybean plants; severely affected seedlings wither and die. This pest has only one generation per year. It overwinters as pupae in root bark tumors of soybean or in soil cracks; in mid-to-late May of the following year, it emerges as adults, lays eggs at the soybean roots, and hatches larvae that damage the soybean seedling roots. Control method: use seed dressing with chemicals to prevent larvae; dress seeds with 40% dimethoate emulsifiable concentrate at 0.7% of the seed weight, mix with water and spray, stirring while spraying. If dressing

Control method: use seed dressing with chemicals to prevent larvae; dress seeds with 40% dimethoate emulsifiable concentrate at 0.7% of the seed weight, mix with water and spray, stirring while spraying. For example, to dress 100 kg of soybean seeds, use 0.7 kg of the pesticide, add 4 kg of water, spray with a sprayer, stir while spraying, then spread out to dry.

During the peak emergence of adults, use 80% dichlorvos emulsifiable concentrate at 1000 times dilution and spray for control. Spray 40 kg of the solution per 667 sq m.
