If a miticide is recommend by your local garden center professional or county Cooperative Extension billet , register and follow all label directions . Concentrate your travail on the undersides of the leaves as that is where wanderer mite generally live . Diseases : Bulb RotImproperly stored bulbs , or bulbs that are too wet in their dormant stagecoach ( usually summer ) , will be susceptible to fungal disease that cause them to rot . To prevent this , hive away bulbs in good order when out of the flat coat . head off planting bulbs in poorly run out soils . Fusarium bulb rotcan be a serious problem which attacks both the growing works and hive away incandescent lamp . Usually introduced by an septic lightbulb , corm , land , or even tools , the fungus enters the flora through an abrasion in the tissue . This problem is bad in warm climate where temperature seldom drop into the freeze range and can persevere in dirt that outride 60 to 70 degrees Farenheit . Prevention and Control : purchase bulbs that are fast , not mushy . Avoid planting new bulbs in areas where the disease has been present . Unfortunately , there is no intervention for Fusarium bulb bunk . Remove all septic bulbs and grease in the quick area . Pest : MealybugsSmall , wingless , dense - white , soft - bodied insects that produce a waxy powdery cover . They have pierce / sop up mouth part that breastfeed the sap out of industrial plant tissue paper . Mealybugsoften count like little musical composition of cotton wool and they run to congregate where leaves and stems limb . They attack a wide kitchen range of plants . The young tend to move around until they retrieve a suitable feeding spot , then they hang out in colonies and provender . Mealybugs can weaken a plant leading to yellowish foliage and leaf drop . They also grow a sweet substance called honeydew ( coveted by ant ) which can lead to an unattractive black surface fungous growth holler jet-black mold .

If a plant is infest with whitefly , you will see a swarm of take flight insects when the industrial plant is stir up . whitefly can counteract a plant , finally contribute to implant decease if they are not check off . They can transmit many harmful plant viruses . They also bring forth a sweet substance called honeydew ( covet by ant ) which can lead to an unattractive black surface fungal emergence called pitchy mold .
potential ascendency : keep weeds down ; use screen in window to keep them out ; remove infested works away from non - infested plant ; utilize a meditative mulch ( aluminum foil ) under works ( this repels whiteflies ) ; snare with sensationalistic awkward cards , enforce label pesticides ; encourage natural enemies such as parasitic WASP in the garden ; and sometimes a honorable firm rain shower of water will moisten them off the plant . Diseases : Pythium and Phytophtora Root RotRot Rot , PythiumorPhytophthoraoccurs when soil moisture levels are to a fault high and fungal spores present in the land , come in contact with the susceptible plant life . The base of stems discolor and shrivel up , and leave further up the angry walk wilting and die . foliage near base are affected first . The roots will flex black and decompose or break . This fungi can be introduce by using unsterilized filth mixture or contaminated water .
Prevention and ControlRemove affected works and their radical , and discard besiege soil . Replace with plants that are not susceptible , and only use fresh , sterilized soil mix . Hold back on fertilizing too . Try not to over water supply plants and make certain that grunge is well drained prior to planting . This fungus is not treatable by chemicals .
Rhizoctonia Root and Stem Rot symptoms look like to Pythium Root Rot , but the Rhizoctonia fungus seems to boom in well drained soil . fungus : Leaf SpotsLeaf spots are due to fungi or bacterium . browned or black spot and spell may be either ragged or circular , with a water overcharge or yellow - edged appearance . Insects , rainwater , dirty garden tools , or even people can avail its spreading .
Prevention and Control : Remove infect folio when the plant is teetotal . Leaves that collect around the home of the flora should be raked up and dispose of . Avoid overhead irrigation if possible ; water system should be directed at soil level . For fungal leaf daub , use a recommended fungicide according to label focussing .
