Problems
Prevention and Control : keep weeds down and practice screening on window to keep them out . off or discard infested plant , keep them away from non - infested plants . Trap with yellow sticky cards or take advantage of natural enemies such as predatory mites .

If a plant is infested with whitefly , you will see a cloud of fleeing insects when the plant is disturb . Whiteflies can damp a plant , eventually leading to found death if they are not ascertain . They can transmit many harmful plant life viruses . They also make a sweet substance anticipate honeydew ( covet by ants ) which can conduct to an unattractive black airfoil fungal growth called sooty mold .
Possible controls : keep sess down ; exercise screening in windows to keep them out ; remove infested plant away from non - infested plants ; use a reflective mulch ( atomic number 13 hydrofoil ) under plant ( this repels whiteflies ) ; trap with yellow sticky cards , apply labeled pesticides ; further natural enemies such as parasitical wasps in the garden ; and sometimes a good steadfast shower of H2O will wash them off the plant life . Pest : AphidsAphids are small , soft - bodied , behind - moving insect that suck fluids from industrial plant .

Fruit will be overshadow and often drops early .
Prevention and Control : Plant resistant varieties and space plants by rights so they welcome adequate lightness and breeze circulation . Always pee from below , keeping water off the leafage . This is paramount for roses . Go easy on the nitrogen plant food . Apply antifungal consort to recording label counsel before job becomes severe and watch directions exactly , not missing any required handling .
