INTRODUCTION We attempted to supplement traditional insecticide spraying by treating peridomiciliar food sources with a powder formulation. METHODS Two groups of houses were treated with deltamethrin suspension concentrate (SC), one of which had its primary peridomestic food sources treated with deltamethrin 2P. RESULTS Triatoma brasiliensis was the most commonly captured triatomine. Birds,...

Vacuum plasma spraying (VPS) is an industrial technique used to coat substrates with a wide range of materials for numerous applications. Historically, vacuum plasma spraying processes have been open-loop processes with, at most, closed-loop control of the spray parameters. Such processes would benefit from closed-loop control as the issues of process repeatability and coating quality could be ...

The objective of the present study is to investigate the impact of spraying boric acid on vegetative and reproductive growth of ‘Camarosa’ strawberry (Fragaria × ananassa Duch.). The strawberry plants were sprayed with Boric acid at 0 (control), 50 and 100 mg L-1 at 30 days after planting. In general, results indicated that spraying plants with boric acid had a significant effect on yield, frui...

An experiment was conducted in order to evaluate the effects of Se spraying on yield and growth indices of wheat under drought stress condition, in agriculture and natural resource research center of Tehran province in 2011-12. A split plot layout within randomized complete block design with three replications were used. main plots were three irrigation treatments (normal irrigation, non-irriga...

Mosquito control operators in France are mainly public and have at their disposal a wide range of spraying techniques to control mosquitoes. Due to the lack of commercial solutions, and in order to meet technical objectives and comply with regulations, they look to continuously improve their spraying application techniques. In the framework of the European Life+ project LIFE08 ENV/F/000488, the...

In the present study we have examined the influence of single spraying with simulated acid rain (pH 1.8) on the content of main lipid classes and their fatty acid composition in the thylakoid membranes of bean plants. Acid stress caused considerable changes in the investigated parameters. A decline in the content of linolenic acid, a highly unsatureted fatty acid which is an indicator of lipid ...

The residue levels of Endrin were estimated for two vegetables, i.e., raddish (Raphanus sativus) and cabbage (Brassica oleracia). Samples were collected from fields and markets. The disappearance of endrin in raddish was also noted after spraying. Ten percent of raddish and 30 percent samples of cabbage were found to contain large amounts of the insecticide ranging from199.4 ± 6.8 to 388.7 ± 16...

Original scientific paper In this paper, influence of flame spraying and fusing on microstructure of substrates made from heat treated carbon steel C45, a heat treated low alloyed 42CrMo4 steel and stainless austenitic steel X6CrNiMo18-10-2, has been investigated. Flame spraying and fusing is a deposition technique commonly applied to nickel-base self-fluxing alloys (NiCrBSi alloys). Because of...

This work focuses on the development of a user interface suitable for targeted spraying, using a robot that is teleoperated along the vineyard rows. A prototype of the spraying interface was developed and the usability of three different interaction modes was investigated. Fifty participants were asked to use the three devices to select grape clusters taken from a simulated robot moving along r...
