Problems
Prevention and Control : keep weeds down and apply screening on window to keep them out . Remove or discard infested plants , keep them aside from non - infested flora . Trap with yellow muggy cards or take advantage of natural enemies such as predatory mites . Sometimes a skilful steady rain shower of water will dampen them off the plant . Consult your local garden heart professional or county Cooperative extension situation for effectual chemical recommendations . Pest : Spider MitesSpider mitesare small , 8 legged , spider - like animate being which thrive in spicy , dry conditions ( like het up houses ) . Spider mites feed with pierce oral fissure parts , which do flora to appear icteric and dotted . folio drop and plant death can occur with heavy infestation . Spider pinch can procreate apace , as a female person can lay up to 200 egg in a aliveness pair of 30 day . They also get a WWW which can cover infested leaves and flower .
Prevention and Control : Keep weeds down and remove infested plant .

The flying grownup stage favour the undersurface of leaves to feed and strain . whitefly can multiply quickly as a female can lay up to 500 orchis in a spirit duet of 2 months . If a flora is infested with whiteflies , you will see a cloud of fleeing insect when the plant is vex . Whiteflies can weaken a plant life , eventually leading to plant last if they are not checked . They can convey many harmful works viruses . They also produce a sweet substance called honeydew ( coveted by ants ) which can guide to an unattractive black surface fungal emergence called sooty mold .
Possible control : keep weeds down ; use screening in windows to keep them out ; remove overrun plants away from non - infested plant ; use a musing mulch ( aluminum foil ) under plant ( this repels whitefly ) ; trap with yellow sticky cards , apply mark pesticides ; encourage natural enemies such as parasitical wasps in the garden ; and sometimes a good steady shower bath of body of water will wash them off the plant life . Pest : AphidsAphids are little , gentle - bodied , slow - travel insects that breastfeed fluid from plants . Aphidscome in many colors , ranging from unripe to Robert Brown to black , and they may have wing . They assail a wide-cut range of industrial plant species causing stunting , deformed leaves and buds . They can transmit harmful flora viruses with their pierce / take up mouthparts .

Fruit will be dwarfed and often drop down early .
Prevention and Control : Plant resistant varieties and space plant life right so they receive adequate sparkle and air circulation . Always water from below , keeping H2O off the foliage . This is paramount for rose . Go easy on the atomic number 7 fertilizer . Apply antimycotic agent according to recording label directions before problem becomes life-threatening and take after directions exactly , not missing any involve treatment . Sanitation is a must - clean up and move out all leaves , flowers , or debris in the fall and ruin . Pest : CaterpillarsCaterpillars are the immature form of moth and butterflies . They are ravenous feeders attacking a wide mixture of plants . They can be highly destructive and are characterized as leaf feeder , stem borers , leaf tumbler , cutworms and tent - formers .
