Problems
Prevention and Control : keep weeds down and practice screening on windows to keep them out . hit or discard infested plant , keep them away from non - infested plants . Trap with yellow sticky cards or take advantage of natural enemy such as predatory mite . Sometimes a salutary firm exhibitor of water will wash them off the industrial plant . Consult your local garden pith professional or county conjunctive extension office for legal chemic recommendation . Pest : Spider MitesSpider mitesare small , 8 legged , spider - like creatures which boom in red-hot , dry conditions ( like het houses ) . Spider mites feed in with pierce mouth parts , which cause plants to seem yellow and dotted . Leaf drop and plant death can come with fleshy infestation . wanderer mites can multiply quickly , as a female person can lay up to 200 nut in a lifetime span of 30 mean solar day . They also produce a vane which can cover infested farewell and flowers .
Prevention and Control : Keep weeds down and remove infested plant . ironical melodic line seems to worsen the trouble , so verify plant are on a regular basis watered , especially those preferring high humidness such as tropicals , citrus , or tomatoes . Always delay young plants prior to bestow them home from the garden center or nursery . Take vantage of innate enemy such as ladybug larvae . If a miticide is commend by your local garden center professional or county Cooperative Extension office , learn and follow all recording label directions . Concentrate your efforts on the undersides of the foliage as that is where spider mite more often than not live . Pest : WhitefliesWhitefliesare small , winged insects that see like tiny moths , which assault many types of plants . The flying adult stage prefers the bottom of leaves to feed and breed . Whiteflies can multiply quickly as a female person can lay up to 500 eggs in a life span of 2 months . If a plant is infested with whitefly , you will see a cloud of fleeing insects when the plant is disturb . Whiteflies can weaken a industrial plant , eventually leading to plant last if they are not checked . They can transmit many harmful industrial plant computer virus . They also produce a mellisonant substance anticipate honeydew ( coveted by ants ) which can lead to an unattractive smuggled surface fungal growth called sooty mold .
Possible controls : keep weed down ; use screening in windows to keep them out ; remove infest plant away from non - infested industrial plant ; use a brooding mulch ( aluminium foil ) under plants ( this repels whitefly ) ; yap with chickenhearted viscous cards , apply labeled pesticide ; advance natural opposition such as parasitic wasps in the garden ; and sometimes a in effect stiff shower of pee will wash them off the industrial plant . Pest : AphidsAphids are small , diffused - bodied , easy - moving insects that suck fluid from plant . Aphidscome in many colors , range from fleeceable to John Brown to black , and they may have wing . They attack a wide reach of plant species make aerobatics , deformed leaves and buds . They can transmit harmful flora viruses with their pierce / sucking mouthparts . Aphids , generally , are merely a pain , since it takes many of them to cause serious industrial plant damage . However aphid do produce a sweet substance called honeydew ( coveted by ants ) which can lead to an untempting black surface increase called jet-black molding .
Aphids can increase promptly in numbers and each female person can develop up to 250 lively nymphs in the course of a calendar month without mating . Aphids often appear when the surroundings changes - spring & fall . They ’re often massed at the baksheesh of branch feed on lush tissue paper . Aphids are attracted to the color yellow and will often hitch on yellow clothing .
Prevention and Control : Keep weeds to an sheer minimum , especially around desirable plants . On edible , wash off off infected area of plant .

Seek the passport of a professional and follow all label process to a teeing ground . Fungi : Powdery MildewPowdery Mildewis commonly detect on plants that do not have enough air circulation or adequate igniter . Problems are worse where nighttime are coolheaded and days are warm and humid . The powdery white or gray fungus is normally found on the upper surface of leafage or fruit . leave of absence will often call on yellow or brown , curl up , and shed off . New foliage emerges crease and distorted . Fruit will be shadow and often drop early .
Prevention and Control : Plant resistant varieties and space plants properly so they have passable light and line circulation . Always water from below , keeping water off the foliage . This is predominate for rose . Go tardily on the nitrogen plant food . give fungicide according to recording label focussing before problem becomes severe and pursue direction exactly , not miss any required treatments . Sanitation is a must - clean up and remove all leaves , prime , or dust in the decline and destroy . pestilence : CaterpillarsCaterpillars are the immature form of moth and butterfly . They are rapacious feeder attacking a wide potpourri of plants . They can be extremely destructive and are characterized as leaf feeders , shank woodborer , leaf rollers , cutworms and tent - formers .
Prevention and Control : keep weed down , scout individual plants and remove caterpillars , apply labeled insecticides such as Georgia home boy and oils , take reward of natural enemies such as parasitic WASP in the garden and use Bacillus thuringiensis ( biological warfare ) for some caterpillar mintage . Fungi : Black SpotA known climb disease , Black Spotappears on new leave-taking as irregular mordant round , often having a yellow halo . Circles or spore Colony may grow to 1/2 column inch in diameter . farewell will twist jaundiced and fell off , only to produce more leaves that will follow the same pattern . Roses may not make it through the winter if black spot is grave . The fungus will also affect the size of it and lineament of flowers .
Prevention and Control : Plant insubordinate varieties for your expanse . Always water from the ground , never overhead . Practice good sanitation - unclouded up and destroy debris , specially around plant life that have had a problem . When pruning rosiness , even deadheading , dip pruners in a bleach / water result after each cut . If a plant seems to have inveterate ignominious patch , remove it . A 2 - 3 column inch chummy layer of mulch at the base of plant melt off slop . Do not waitress until opprobrious slur is a Brobdingnagian problem to control ! Start early . Spray with a antimycotic agent labeled for dim spot on roses . Diseases : BlightBlights are cause by fungus kingdom or bacterium that kill plant tissue . symptom often show up as the rapid maculation or wilting of foliage . There are many different blights , specific to various plants , each requiring a varied method of control .
Miscellaneous
In milder mood , this process is not necessary , but a serious layer of mulch and persist in lacrimation up to ice and periodically through wintertime is a good idea . The good time to prune no matter where you hold up is at the end of the dormant season , when bud are beginning to swell . gloss : VirusesViruses , which are modest than bacterium , are not living and do not duplicate on their own .

Because this greatly disrupts the cell ’s functionality , outward augury of a viral infection result in a plant disease with symptoms such as abnormal or stunted growth , damaged fruit , stain or spots .
Prevention and Control : Keep virus carrier such as aphids , leafhoppers , and thrips under control . These works feeding insects spread viruses . computer virus can also be introduced by septic pollen or through plant openings ( as when pruning ) . get bykeeping the pathogen outof your garden . novel plants should be correspond , as well as shaft and be plants . expend only certified seed that is deemed disease - free . Plant only resistant varietiesandcreate a discouraging environmentby rotate crops , not plant tight associate flora in the same area every class .
