Effects of sprayer configuration on efficacy for the control of scab on crabapple using electron beam analysis.
Foliar diseases like apple scab result in significant economic losses to growers each year. Assessment in past studies involved only macroscopic disease ratings. More complete knowledge of the fate and behavior of fungicide has been needed to reduce pesticide use with less off-target contamination. Field studies were conducted in a production nursery for over 4 years. A moderately susceptible c...
متن کاملWhitefly control potential of Eretmocerus parasitoids with different reproductive modes
A major component of the evaluation of biological control agents is the study and comparison of their biology, including the reproductive mode. In hymenopteran parasitoids, reproductive modes include thelytoky and arrhenotoky. Since a thelytokous population produces only females, it is assumed that they may be better suited for biological control than an arrhenotokous population. Here we compar...
متن کاملTYLCV-resistant Tomato Cultivar Trial and Whitefly Control Strategies
Tomato yellow leaf curl virus (TYLCV) and tomato spotted wilt virus (TSWV) are common diseases of tomato in Florida. TYLCV occurs in central and southern Florida whereas TSWV occurs in northern Florida and throughout all states of the southeastern USA. TYLCVresistant cultivars and advanced breeder’s varieties are available for commercial use, but vegetable producers don’t often use them. A vari...
متن کاملRNA Interference based Approach to Down Regulate Osmoregulators of Whitefly (Bemisia tabaci): Potential Technology for the Control of Whitefly
Over the past decade RNA interference (RNAi) technology has emerged as a successful tool not only for functional genomics, but in planta expression of short interfering RNAs (siRNAs) that could offer great potential for insect pest management. The diet of insects feeding exclusively on phloem sieves contains water and sugars as main components, and the uptake of the liquid food greatly depends ...
متن کاملEffect of Parasitoid Release Pattern on Whitefly (homoptera: Aleyrodidae) Control in Commercial Poinsettia
Under commercial poinsettia production conditions we compared two patterns of parasitoid release for the aphelinid whitefly parasitoid Eretmocerus eremicus Rose and Zolnerowich. We compared the currently used pattern of a fixed weekly release number (3 females per plant per week) to an experimental pattern in which more parasitoids were released early in the crop (wks 1-8), followed by a lower ...
