The infestation of sucking pest (aphids spp.) 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 spp.) cause 70 to 80 percent 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).
