Foliar sprays containing 3,000 or 4,000 ppm oxamyl applied before inoculation with Meloidogyne hapla completely protected tomato plants from intection for up to 36 days but sprays containing 1,000 or 2,000 ppm provided only partial protection. Postinoculation sprays were less effective than preinoculation sprays but they decreased the numbers of females and their rate of development and increas...

-Theoretical and experimental studies dealing with the spray ignition phenomena are reviewed. Two major topics covered are external-source ignition of liquid fuel sprays and spontaneous spray ignition. Experimental and theoretical investigations of external-source ignition of sprays employing different configurations are discussed first. Three major topics included here are: (i) ignition of qui...

Outdoor residual sprays are among the most common methods for targeting pestiferous ants in urban pest management programs. If impervious surfaces such as concrete are treated with these insecticides, the active ingredients can be washed from the surface by rain or irrigation. As a result, residual sprays with fipronil and pyrethroids are found in urban waterways and aquatic sediments. Given th...

Evidence for the role of silica in plants is reviewed with respect to the application of silicate based sprays in biodynamic agriculture. There is research indicating improved resistance to pests, disease, drought and other stresses on plants from application of silica fertilisers and sprays. There is also evidence of improved nutrient uptake. Experiments with field grown lettuce were undertake...

Bait sprays containing the toxicant spinosad (GF-120) were applied to citrus groves in the Rio Grande Valley of Texas where Mexican fruit flies were detected in surveillance traps. The sprays were applied as a supplement to a continuous sterile insect release program. Sterile fly captures were 47-63% lower in the treated groves compared with control groves. Eight of 10 secondary pest population...

BACKGROUND Pesticide use patterns are essential inputs into human pesticide exposure models. Currently, data included for modeling purposes have mostly been collected in cross-sectional surveys. However, it is questionable whether responses to one-time surveys are representative of pesticide use over longer periods, which is needed for assessment of health impact. This study was designed to eva...

Introduction: One of the medications used by patients with dyspnea and asthma is sprays whose the way of application is very important. If these medications are not used properly, they will not be effective. The purpose of this study was to investigate the correct or incorrect use of sprays by patients. Material and Method: This double-blind observational analytical study was conducted on patie...

Objective Intranasal steroid sprays (INSS) are frequently prescribed for treating inferior turbinate hypertrophy (ITH). Complications due to the long-term application of INSS such as crusting, epistaxis, nasal mucosa dryness, and septal perforation may occur. Predicting patients who would benefit from INSS early might lower treatment costs and complication rates. We examined the predictive valu...
