Which one of the following causes more wastages of herbicide by drift
Answer & Solution
Correct Answer:
Option
B
In agriculture, herbicides are often applied using various types of sprayers or dusters. When it comes to herbicide wastage through drift, the Ultra-low volume (ULV) sprayer is the most problematic.
- High volume sprayer: This type of sprayer typically produces larger droplets, which are less prone to drifting. While there might be some wastage due to drift, it is generally lower compared to other methods.
- Ultra-low volume (ULV) sprayer: These sprayers produce extremely fine droplets, which are highly susceptible to drift. Even slight wind or air currents can carry these droplets away from the target area, resulting in significant herbicide wastage.
- Hand sprayer: When used properly, hand sprayers can minimize drift since the applicator has more control over the direction and intensity of spraying. However, if not used correctly, drift can still occur.
- Duster: Dusters are used for applying dry formulations of herbicides. While they may not directly contribute to liquid drift, there can still be wastage due to dispersion of dry particles by wind.
