Abstract:
A 2-year study was conducted to evaluate relative effect of color mulches to potato/tomato psyllid, Paratrioza cockerelli (Sulc.) (Homoptera: Psyllidae), on tomato plant in Fort Collins, Colorado (USA). In the first year, an aluminum mulch and white plastic mulch resulted in significant reduction on potato/tomato psyllids on tomatoes (c.v. ‘Celebrity’) comparing with the black plastic mulch and untreated check. The white plastic mulches continued to suppress psyllids in the second evaluation. In the second year, an aluminum mulch significantly decreased number of psyllid on tomato plants (c.v. ‘Roma’) comparing with other treatments (straw, black plastic, bare ground control). In conclusion, the aluminum and white plastic mulch can be used as an alternative cultural control to the chemical control for controlling potato/tomato psyllid in home garden tomato plants in Colorado.
