Aphids control in Fennel:
Aphids suck the cell sap from the plants. Due to secretion of honeydew like substance from the insects, a black sooty mould is developed and hinders the plant photosynthetic activity of the plants. The growth of plants is stunted. According to very old recommendation given by the Gujarat Agril. University, spray dimethoate 30 EC @ 10 ml per 10 lit of water on 50 percent plants having flowering. The higher activity of honeybees is observed during 12 noon to up to 4.00 evening and hence avoid the spraying during this period.
