Problems
Prevention and Control : keep weeds down and use test on windows to keep them out . dispatch or discard infested plants , keep them away from non - infested plant . Trap with chickenhearted sticky cards or take reward of natural foe such as predatory mites . Sometimes a expert unbendable shower of water will wash away them off the plant . Consult your local garden center professional or county Cooperative extension situation for legal chemic good word . Pest : Spider MitesSpider mitesare small , 8 legged , spider - like creatures which thrive in live , ironic condition ( like heated sign of the zodiac ) . Spider mites feed with piercing mouth parts , which induce plants to appear chickenhearted and stippled . foliage pearl and plant death can occur with heavy infestations . wanderer mites can multiply quickly , as a female can lay up to 200 eggs in a living pair of 30 days . They also produce a web which can brood infested leaves and flowers .
Prevention and Control : Keep weeds down and remove infested plant .

Whiteflies can sabotage a flora , finally guide to plant last if they are not check . They can transmit many harmful plant viruses . They also bring forth a sweet message holler honeydew ( coveted by emmet ) which can lead to an unattractive black surface fungal ontogeny called sooty mold .
Possible controls : keep weeds down ; use screening in window to keep them out ; remove infested plants aside from non - infested plants ; use a reflective mulch ( atomic number 13 foil ) under plant life ( this repels whitefly ) ; trap with scandalmongering pasty add-in , practice labeled pesticides ; promote natural enemies such as parasitic wasps in the garden ; and sometimes a secure unbendable cascade of weewee will wash them off the plant life .

They can transmit harmful plant virus with their pierce / suck mouthpart . Aphids , in general , are just a pain in the neck , since it takes many of them to cause serious plant damage . However aphid do bring about a scented heart called honeydew ( coveted by pismire ) which can go to an unattractive smuggled Earth’s surface growth called sooty mold .
Aphids can increase apace in numbers and each female person can produce up to 250 live nymphs in the path of a calendar month without mating .

Fungi : Powdery MildewPowdery Mildewis usually regain on plants that do not have enough air circulation or adequate light . problem are bad where nights are cool and days are warm and humid . The powdery lily-white or white-haired fungus is commonly found on the upper surface of leaves or yield . leave will often wrick lily-livered or chocolate-brown , curl up , and drop off . New leafage emerges crinkled and perverted . Fruit will be dwarfed and often drops early .
Prevention and Control : Plant resistant varieties and space plant properly so they welcome adequate light and atmosphere circulation . Always water from below , keeping water off the foliage . This is predominate for roses . Go easy on the nitrogen fertilizer . Apply fungicides agree to recording label focusing before problem becomes wicked and follow directions exactly , not missing any required intervention . Sanitation is a must - clean up and murder all leaves , flower , or debris in the fall and put down . Pest : CaterpillarsCaterpillars are the unripened course of moth and butterfly . They are voracious feeders attack a wide variety of works . They can be extremely destructive and are characterized as leafage feeders , stem turn borers , leaf roller , cutworms and tent - former .
Prevention and Control : keep weeds down , scout single plant and remove Caterpillar , employ labeled insecticide such as liquid ecstasy and oils , take reward of natural enemy such as parasitic wasps in the garden and use Bacillus thuringiensis ( biological war ) for some caterpillar species . Fungi : Black SpotA known rose disease , Black Spotappears on young leaves as irregular pitch-dark circles , often feature a scandalmongering halo . circle or spore colony may get to 1/2 inch in diameter .
