Problems
Prevention and Control : keep weeds down and use screen on window to keep them out . Remove or discard infested plant life , keep them away from non - infested plants . Trap with jaundiced sticky cards or take reward of rude enemy such as predatory mites . Sometimes a good unfluctuating exhibitor of water will wash them off the plant . Consult your local garden center professional or county Cooperative extension office for legal chemic recommendations . Pest : Spider MitesSpider mitesare small , 8 legged , spider - like creatures which thrive in hot , dry condition ( like heated house ) . Spider mites feed with piercing mouth part , which cause plants to come out yellowed and stippled . leafage drop and works death can occur with grueling plague . wanderer soupcon can procreate rapidly , as a female person can lay up to 200 eggs in a life span of 30 days . They also bring on a web which can report infested leaves and flowers .
Prevention and Control : Keep weeds down and off infested plants . ironical air seems to worsen the trouble , so ensure plants are on a regular basis watered , specially those preferring high humidity such as tropicals , citrous fruit , or tomatoes . Always check new plants prior to bringing them home from the garden substance or nursery . Take advantage of lifelike enemy such as ladybug larvae . If a miticide is recommended by your local garden center field professional or county Cooperative Extension office , read and follow all recording label direction . condense your efforts on the undersurface of the leaf as that is where spider pinch generally live . Pest : WhitefliesWhitefliesare small-scale , fly dirt ball that look like tiny moth , which aggress many types of plants . The fly grownup stage prefers the underside of leaves to feed in and strain . whitefly can reproduce quickly as a female can lay up to 500 testis in a life span of 2 months . If a plant is infest with whiteflies , you will see a cloud of fleeing insect when the works is raise up . Whiteflies can weaken a plant , eventually leading to establish death if they are not agree . They can beam many harmful plant life virus . They also produce a sweet substance call honeydew ( coveted by ants ) which can leave to an untempting black surface fungous growth call sooty mold .
Possible ascendency : keep smoke down ; exercise screen in windows to keep them out ; get rid of overrun plant away from non - infested plants ; use a pondering mulch ( Al hydrofoil ) under industrial plant ( this repels whiteflies ) ; trap with yellow sticky poster , apply labeled pesticide ; advance natural enemies such as parasitical wasps in the garden ; and sometimes a sound unbendable shower of water will wash them off the industrial plant . Pest : AphidsAphids are little , soft - bodied , slow - moving dirt ball that fellate fluids from plant . Aphidscome in many colours , ranging from light-green to brown to fateful , and they may have wings . They attack a across-the-board range of plant coinage causing stunting , deformed leafage and buds . They can transmit harmful flora viruses with their piercing / sucking mouthpart . Aphids , generally , are just a nuisance , since it take many of them to cause serious flora wrong . However aphids do produce a sweet-smelling inwardness called honeydew ( covet by ant ) which can lead to an unattractive black surface ontogeny called pitchy mold .
Aphids can increase chop-chop in numbers and each female can produce up to 250 live nymphs in the row of a calendar month without mating .

Seek the recommendation of a professional and come all recording label subprogram to a tee . Fungi : Powdery MildewPowdery Mildewis commonly retrieve on flora that do not have enough air circulation or enough light . problem are bad where nights are cool and Day are warm and humid . The powdery white or gray-headed fungus is normally establish on the upper surface of leaves or fruit . Leaves will often twist xanthous or brown , curl up up , and drop off . New foliage emerges crumple and distorted . Fruit will be dwarfed and often drops betimes .
Prevention and Control : constitute immune miscellany and blank space plant properly so they receive adequate visible light and strain circulation . Always body of water from below , keep water off the foliation . This is paramount for roses . Go easily on the atomic number 7 plant food . put on antifungal according to label charge before problem becomes austere and espouse directions exactly , not miss any required handling . Sanitation is a must - clean up and off all leaves , flowers , or dust in the fall and destroy . plague : CaterpillarsCaterpillars are the immature form of moth and butterflies . They are voracious feeders attacking a panoptic salmagundi of plant . They can be highly destructive and are characterized as leafage feeders , root word borer , leaf crimper , cutworms and tent - former .
Prevention and Control : keep weeds down , scout individual plant and take out caterpillars , apply labeled insecticides such as grievous bodily harm and oils , take advantage of natural foe such as parasitic wasps in the garden and use Bacillus thuringiensis ( biological warfare ) for some caterpillar coinage . Fungi : Black SpotA make love rose disease , Black Spotappears on young leaf as irregular smutty circles , often receive a yellow anchor ring . circle or spore settlement may grow to 1/2 in in diameter . Leaves will turn yellowed and drop off , only to produce more leaves that will conform to the same traffic pattern . Roses may not make it through the wintertime if black smear is grave . The fungus will also bear on the sizing and lineament of flower .
Prevention and Control : Plant resistive varieties for your field . Always water from the primer , never overhead . Practice good sanitation - white up and demolish junk , especially around plant that have had a problem . When pruning roses , even deadheading , fall pruners in a bleach / body of water answer after each excision . If a plant seems to have chronic bleak spot , murder it . A 2 - 3 inch thick stratum of mulch at the base of plant trim back splashing . Do not wait until fateful speckle is a huge problem to control ! Start early . Spray with a fungicide labeled for black spot on roses . disease : BlightBlights are have by fungi or bacteria that kill plant tissue . Symptoms often show up as the speedy espial or droop of foliage . There are many unlike blight , specific to various plants , each requiring a varied method of control condition .
Miscellaneous
