This study tested the efficacy of five different phosphites (calcium, copper, magnesium, potassium and zinc/manganese phosphites) a fungicide Fosetyl-Aluminum to inhibit bacterial speck disease severity caused by Pseudomonas syringae pv. tomato (Pst) on leaves. The were applied at recommended doses Pst inoculated plants in pots foliar spraying one-week intervals for total 4 weeks. kept controll...

The adsorption study was conducted on three Japanese soils with different soil properties to characterize the adsorption pattern of Arsenic (As). Double tube method was used to find out the effect of soil moisture levels on As adsorption. For this study, besides double tube method, conventional batch method also was used. The As adsorption showed two phase kinetics. An initial and rapid adsorpt...

Thermal spraying coating techniques have lately emerged as very effective surface protection technology to apply protective coatings for corrosion and wear resistance applications. These coatings have gained more importance in recent past. Advances in powder and wire production have resulted in development of various types of surface coatings with excellent wear and corrosion resistance propert...

The experimental study is done for technological parameters of high-melting metal arc spraying to study the influence of spraying current, spraying voltage and wire feed voltage on spraying arc and the influence of spraying current on coating temperature and analyze theoretically the distribution rules of spray gun jet speed field and temperature field and their influencing factors. The results...

Distance learning presents great potential for mitigating field problems on pesticide application technology. Thus, due to the lack of teaching material about pesticide spraying technology in the Portuguese language and the increasing availability of distance learning, this study developed and evaluated a computer program for distance learning about the theory of pesticide spraying technology u...

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...

BACKGROUND Establishing the sources of reinfestation after residual insecticide spraying is crucial for vector elimination programs. Triatoma infestans, traditionally considered to be limited to domestic or peridomestic (abbreviated as D/PD) habitats throughout most of its range, is the target of an elimination program that has achieved limited success in the Gran Chaco region in South America....

For the spraying mobile robot working in greenhouse, due to the inconsistency of drive motors and the rough walking surface, it is easy to track off. For the liquidity of pesticide, the load always changes even the speed jumps. Because of these uncertainties, external disturbances and the difficulty of constructing the system dynamic model, it is hard to implement the trajectory tracking contro...
