Detail:

The infestation of sucking pest (aphids) is seen in fennel (Foeniculum vulgare) when the crop is one-and-a-half to three months old. Some farmers call it "sakariya".Sometimes the sucking pest aphids cause 70-80 % damage in crops like fennel (Foeniculum vulgare) and mustard (Brassica juncea). According to the farmer, when the wind is mild in the morning, green or dried leaves of eucalyptus are burnt in the farm to create smoke. If needed, the practice is repeated after one week. As it spreads, the smoke eliminates sucking pest aphids. Dr. Amrutlal Parabiya says the smell of eucalyptus (Eucalyptus globulus) expels the pests.)
