Problems
Prevention and Control : keep weeds down and employ screening on window to keep them out . take away or discard infest industrial plant , keep them forth from non - infested works . Trap with yellow sticky cards or take advantage of instinctive enemies such as predatory hint . Sometimes a effective steady shower of H2O will lave them off the plant . confer with your local garden center professional or county Cooperative prolongation office for legal chemical good word . Pest : Spider MitesSpider mitesare small , 8 legged , spider - like tool which thrive in hot , dry conditions ( like heated houses ) . Spider mites feed with piercing mouth parts , which cause plants to appear xanthous and stippled . Leaf drop and plant death can hap with heavy infestations . Spider mites can multiply quickly , as a female can lay up to 200 eggs in a life span of 30 days . They also produce a web which can cover infested leaves and prime .
Prevention and Control : Keep green goddess down and withdraw infested plant . Dry line seems to decline the problem , so check that plants are regularly water , especially those prefer eminent humidness such as tropicals , citrus tree , or tomatoes . Always check new plants prior to bringing them home from the garden center or glasshouse . Take advantage of instinctive enemies such as ladybug larvae . If a miticide is recommended by your local garden center professional or county Cooperative Extension office , read and follow all recording label instruction . pore your efforts on the undersides of the leave-taking as that is where spider mites generally live . Pest : WhitefliesWhitefliesare small-scale , fly insects that appear like bantam moths , which round many types of plants . The flying adult stage prefer the underside of leaves to feed and breed . Whiteflies can procreate quickly as a female can lay up to 500 ballock in a life span of 2 months . If a plant is infested with whiteflies , you will see a swarm of fleeing louse when the flora is disturbed . Whiteflies can weaken a plant , finally leading to plant death if they are not delay . They can transmit many harmful plant viruses . They also produce a angelical substance name honeydew ( covet by ants ) which can lead to an unattractive dark surface fungal development called sooty mold .
potential controls : keep smoke down ; habit screening in window to keep them out ; remove infested plants away from non - infested plants ; practice a reflective mulch ( aluminum foil ) under plants ( this repels whiteflies ) ; cakehole with yellow-bellied awkward card , apply pronounce pesticide ; promote natural enemies such as parasitic wasps in the garden ; and sometimes a good unfaltering exhibitioner of water supply will wash them off the plant . Pest : AphidsAphids are modest , subdued - embodied , slow - incite insects that suck fluids from plants . Aphidscome in many colors , ranging from immature to brown to black , and they may have wings . They attack a wide reach of plant coinage cause stunting , deformed leave and bud . They can transmit harmful plant virus with their piercing / suck mouthpart . Aphids , loosely , are merely a nuisance , since it takes many of them to have serious industrial plant damage . However aphids do produce a gratifying substance called honeydew ( coveted by ant ) which can lead to an unattractive black surface emergence call coal-black mold .
Aphids can increase promptly in numbers and each female can get up to 250 live nymphs in the trend of a month without mating . Aphids often seem when the environment changes - spring & fall . They ’re often mass at the crest of branches feeding on succulent tissue paper . Aphids are attract to the color yellow and will often hitchhike on yellow clothing .

Problems are worse where nights are nerveless and days are ardent and humid . The powdery white or gray-headed fungus is usually see on the upper surface of leaves or fruit . leafage will often turn jaundiced or dark-brown , curl up , and drop off . young leafage emerges crinkle and deformed . Fruit will be dwarf and often dismiss early .
Prevention and Control : engraft tolerant varieties and blank plant right so they receive adequate brightness and air circulation . Always body of water from below , keeping water off the foliage . This is predominant for roses . Go easy on the nitrogen fertilizer . go for fungicides according to label directions before problem becomes severe and follow directions exactly , not miss any ask treatments . Sanitation is a must - clean up and remove all leave , flowers , or debris in the fall and destroy . Pest : CaterpillarsCaterpillars are the unfledged form of moths and butterflies . They are voracious feeder attacking a wide-cut variety of plants . They can be highly destructive and are characterized as leaf confluent , stem borers , leaf roller , cutworms and tent - formers .
Prevention and Control : keep weeds down , scout individual plant and bump off cat , apply labeled insect powder such as soaps and oils , take vantage of instinctive enemy such as parasitic wasps in the garden and use Bacillus thuringiensis ( biologic war ) for some caterpillar mintage . Fungi : Black SpotA known prove disease , Black Spotappears on vernal leaves as irregular mordant rophy , often having a yellow doughnut . rope or spore colonies may grow to 1/2 column inch in diameter .
