This sprawling herbaceous plant can grow quite improbable , contact heights of more than 2 pes . The parting of salvia can be purple , green , variegated or even gold , depending on the variety . All varieties of salvia can be trouble by several type of insect pest .
Sweetpotato Whitefly
The sweetpotato whitefly ( Bemisia tabaci ) assail more than just sugared potato , as its name implies . This small insect pest onrush more than 500 coinage of plants let in sage , accord to entomologist with the University of Hawaii . These pests thrust the parting of the salvia and suck the cosh from them , causing the leaves to wither and drop off , and the flora itself to wilt . Heavy infestation can stimulate the sage works to die . In addition , these whiteflies excrete a sticky nub called honeydew , which attracts ants and fungal spores such as jet mold . Finally , whiteflies can also channel plant disease .
Spray the salvia with an insect powder formulate to vote out whiteflies . Make certain to apply the spray to the undersides of the leaves , where larvae are often found . Repeat covering may be needed . rinse off the leaf of the sage plant thoroughly before exhaust them . Note that these finical types of whiteflies are passably difficult to control using chemical substance , accord to horticulturist with the University of Hawaii .
Red and Black Flat Mite
These mites ( Brevipalpus phoenicis ) typically attack the stems of the leaves and plant first , then move on to the leaves themselves , eat on the plant ’s juice and causing the salvia to eventually die . former symptom let in leaf wilt , chocolate-brown or distorted parting , and the death of the middle or inner tissue of the leaves . The alimentation leaves holes in the works and down the surround tissue , sometimes make scabs or sink , dead brown areas on the sage flora .
Flat touch are susceptible to insecticides and can be well killed with chemical way . big infestation may want a 2nd app . They are also tropical louse and do not do well in cold climates . As with all insecticide use , wash the salvia leaves thoroughly before using them in nutrient .
Greenhouse Whitefly
nursery whitefly ( Trialeurodes vaporariorum ) are standardised to sweetpotato whiteflies in that they attack a large number of different types of plant , although they are smaller than their opposite number . These pest are found throughout the creation and feed off of the tomfool of sage and other plants . Unlike the sweetpotato whitefly , however , scathe is often not visible other than a general decline of the works , or the residue of sticky honeydew .
Note that the greenhouse whitefly has regrettably become resistant to several case of synthetic insecticide . For that rationality , plantsman with the University of Hawaii advise using insecticidal soaps or oils to operate this insect . Repeat applications of the soap or oil as need , and wash the leaf thoroughly before consumption .
