Problems
Prevention and Control : keep weeds down and habituate screen on window to keep them out . get rid of or discard infested plant , keep them away from non - infested plants . Trap with yellow-bellied gluey card or take advantage of natural enemies such as predatory tinge . Sometimes a good steady shower of H2O will wash them off the plant . Consult your local garden center professional or county Cooperative extension billet for legal chemical recommendations . Pest : Spider MitesSpider mitesare small , 8 legged , wanderer - like creatures which thrive in hot , dry weather condition ( like heated up houses ) . Spider mites fee with piercing backtalk parts , which make plant life to come along yellow-bellied and flecked . Leaf fall and plant decease can come with grave infestation . wanderer mites can multiply quickly , as a female can lay up to 200 egg in a life span of 30 days . They also produce a web which can cover infested leaves and flowers .
Prevention and Control : Keep weeds down and bump off infested plant . Dry air seems to worsen the problem , so make certain plants are on a regular basis watered , especially those prefer high humidity such as tropicals , citrous fruit , or tomatoes . Always determine new industrial plant prior to bringing them home from the garden eye or nursery . Take reward of rude enemies such as ladybug larvae . If a miticide is advocate by your local garden center professional or county Cooperative Extension office , read and follow all label directions . Concentrate your movement on the undersides of the leaves as that is where spider mites mostly exist . Pest : WhitefliesWhitefliesare small , winged insects that look like midget moth , which attack many type of industrial plant . The flying adult stage favour the underside of parting to feed in and stock . whitefly can multiply apace as a female can lay up to 500 nut in a animation twosome of 2 months . If a plant is infested with whiteflies , you will see a cloud of flee dirt ball when the plant is touch . whitefly can weaken a plant , finally leading to implant destruction if they are not see . They can transmit many harmful flora virus . They also create a scented substance call honeydew ( covet by ants ) which can lead to an unattractive smutty surface fungal growth call jet mould .
potential control : keep weeds down ; use screen in window to keep them out ; take away infest plant away from non - infested industrial plant ; expend a reflective mulch ( atomic number 13 foil ) under plants ( this repels whitefly ) ; trap with yellow muggy cards , use labeled pesticides ; boost natural foe such as parasitic wasp in the garden ; and sometimes a good steady shower of water will wash them off the plant . Pest : AphidsAphids are small-scale , soft - corporal , easy - moving insects that suck in fluids from works . Aphidscome in many colors , ranging from unripe to brown to black , and they may have wing . They round a wide ambit of plant coinage causing acrobatics , deform leaves and buds . They can air harmful plant virus with their pierce / suckle mouthparts . Aphids , generally , are simply a nuisance , since it take many of them to cause serious plant wrong . However aphid do produce a seraphic centre called honeydew ( covet by ants ) which can lead to an unattractive contraband Earth’s surface increase called pitchy mould .
Aphids can increase cursorily in numbers and each female person can produce up to 250 live nymphs in the course of a month without mating . Aphids often appear when the environs changes - spring & crepuscule . They ’re often massed at the tips of arm feed in on succulent tissue .

Fungi : Powdery MildewPowdery Mildewis commonly find on works that do not have enough air circulation or passable light . problem are bad where nights are cool and days are warm and humid . The powdery white or gray fungus is usually discover on the upper aerofoil of leave or yield . Leaves will often turn yellow or brown , curl up , and fell off . New leafage emerge scrunch and malformed . Fruit will be dwarf and often drops early on .
Prevention and Control : imbed resistant varieties and quad works properly so they receive fair to middling light and air circulation . Always water from below , restrain water off the leaf . This is preponderant for roses . Go tardily on the nitrogen fertilizer . utilize fungicides according to label directions before problem becomes severe and follow directions on the nose , not missing any required handling . Sanitation is a must - clean up and remove all leaves , flowers , or debris in the descent and destroy . blighter : CaterpillarsCaterpillars are the immature class of moth and butterflies . They are voracious confluent attacking a full variety of plants . They can be highly destructive and are characterize as folio feeders , stem borers , folio rollers , cutworms and tent - formers .
Prevention and Control : keep widow’s weeds down , picket single industrial plant and get rid of caterpillars , use label insect powder such as soap and oils , take advantage of natural enemies such as bloodsucking wasps in the garden and use Bacillus thuringiensis ( biologic war ) for some caterpillar species . kingdom Fungi : Black SpotA known uprise disease , Black Spotappears on young leaves as irregular black circles , often having a chickenhearted halo . Circles or spore colonies may grow to 1/2 inch in diam . folio will turn over yellow and drop down off , only to produce more leaves that will follow the same pattern . blush wine may not make it through the wintertime if smutty spot is severe . The fungus will also involve the size and quality of flowers .
Prevention and Control : establish resistant varieties for your orbit . Always water from the ground , never overhead . practise good sanitation - clean up and destroy debris , especially around plants that have had a problem . When clip roses , even deadheading , dip pruners in a bleach / H2O solution after each cut . If a plant seems to have chronic dim spot , remove it . A 2 - 3 in heavyset bed of mulch at the Qaeda of industrial plant reduces splosh . Do not await until smuggled fleck is a huge trouble to verify ! Start early . Spray with a antimycotic labeled for black spot on roses . Diseases : BlightBlights are cause by fungi or bacteria that kill plant tissue . Symptoms often show up as the rapid spotting or wilting of foliation . There are many unlike blight , specific to various plants , each requiring a varied method of restraint .
Miscellaneous
