A spray drift model was developed to deliver real time information to the pesticide applicator. The sprayer is equipped with sensors to deliver real time measurement of operational parameters as spray pressure, boom height, horizontal boom movements and geolocalization. The spray droplet size spectrum as a function of pressure was characterized using PDI measurements. Wind speed and direction w...

Plant protection unmanned aircraft vehicles (UAVs) were developed rapidly in China. The operation performances of different models UAVs different. This paper systematically studied droplet deposition distribution; pesticide-mixture utilization rate; operational efficiency; wheat-disease control efficacy; and a comprehensive score three types UAVs, boom sprayer, knapsack sprayer. results showed ...

In order to improve the spraying efficiency of cotton chemical topping agents, a field experiment was conducted compare effects 250 g·L?1 mepiquat chloride aqueous solutions sprayed by T30 unmanned aerial vehicle (UAV) and boom sprayer. The agronomic parameters, pesticide utilization rate, yield, fiber quality were determined. results showed that rates UAV sprayer 48.71% 30.37%, respectively. A...

Chilli (Capsicum annuum L.) is an important vegetable and spice crop belongs to Solanaceae family which grown all over the world. Dried pods contain 36 gms of carbohydrates, 18 proteins, excellent source vitamin A C together provide roughly 160 calories energy per 100 (Narayanan et al., 1999). Area, production productivity in India was 7.43 Lakh ha, 19.14 Tonnes 2576 kg/ha, respectively (Anonym...
