very little information exists in regards to the control options available for potato flea beetles, epitrix spp. this short review covers both chemical and ecological options currently available for control of epitrix spp. synthetic pyrethroids are the weapon of choice for the beetles. however, the impetus in integrated pest management is to do timely (early-season) applications with something ...

Bait stations represent an environmentally friendly attract-and-kill approach to fruit fly population suppression. Recently a novel, visually attractive, rain-fast bait station was developed in Hawaii for potential use against multiple species of pestiferous fruit flies. Here, we compared the efficacy of GF-120 NF Naturalyte Fruit Fly Bait applied either as foliar sprays or onto bait stations i...

A study of the ignition of non-fire-resistant hydraulic fluid sprays was conducted by the National Institute for Occupational Safety and Health. Both an open flame and a hot steel surface were used as the external heat sources. With the open flame as the heat source, the minimum oil temperature and minimum spray nozzle pressure that resulted in an ignition were measured. The effects of the dist...

Field trials were used to investigate the phytotoxicity of foliar sprays of 2,4-D amine to sugarcane. Yield losses of variety NCo 376 resulted from band sprays when 3,3 kg ae/ha was sprayed onto plant or ratoon cane which had unfurled three or more leaves per shoot. The greater the foliar development of the crop at the time of spraying, the greater was the resulting crop loss. At similar stages...

Space sprays for the control of adult mosquito populations are widely used by mosquito control groups throughout the world both for the pest and vector species. In the South-East Asia and Western Pacific regions, adulticiding is especially used to control vectors during epidemic outbreaks of mosquito-borne arboviruses such as dengue and Japanese encephalitis. Space sprays may be applied as ther...

The efficacy of oxamyl in controlling Heterodera schachtii on cabbage was determined by applying various contbinations of soil drenches at 6.7 kg (a.i.)/ha and foliar sprays at 0.04 kg (a.i.)/100 liters of water to cabbage seedlings. Pretransplant drenches provided some control of H. schachtii over a 13-week period. A single foliar spray of oxamyl 1 week before transplanting apparently prevente...

Action threshold-based insecticide spray regimens were evaluated for control of tomato fruitworm (Helicoverpa zea [Boddie]) in freshmarket tomatoes in eastern Virginia in 1998 and 1999. The initial foliar-applied insecticide spray was made based on the presence of X1 H. zea egg on either X2%, X10% or X20% of plants sampled, while subsequent sprays were made on either a weekly basis or only if X...

A field experiment was conducted during Rabi season of 2012-13 at Regional Agricultural Research Station, Lam, Guntur, with an aim to find out the effect of foliar nutrition on water potential, photosynthetic rate, dry matter production and yield of mung bean under receding soil moisture conditions in split plot design with irrigation and no irrigation as main treatments and foliar sprays as su...
