If there are sensitive objects such as bees, mulberry trees and fish ponds around the operation area, it is possible that the pesticides will affect the survival of the sensitive objects, resulting in economic disputes. At this time, the following factors should be considered, and the operation must not be forced.
Wind direction: Sensitive objects should be kept in the upwind direction to reduce risks.
Pesticides: Appropriate pesticides should be selected to reduce the threat to sensitive objects.
Boundary: Sufficient security boundary should be set aside to ensure safety.
When working, be wary of unlabeled pesticides.
The selection of high-quality water-based chemicals, such as suspending agent, water emulsion, microemulsion, etc., can improve work efficiency. At the same time, highly toxic pesticides such as phorate, parathion, methamidophos, and omethoate should not be used, otherwise, personnel poisoning will easily occur due to the high concentration of the liquid.
Taking weeding as an example, a plant protection team carried out destructive weeding of lotus root fields in Hunan Province, China. On that day, the north wind was 2-3, and 55% glyphosate isopropylamine salt, high-efficiency flufenox-ethyl and other chemicals were used for the operation. The operating area was 160 acres, resulting in varying degrees of phytotoxicity of lotus roots and rice within a range of nearly 1000 meters downwind.
Therefore, special attention should be paid to the following issues when carrying out herbicide operations:
Attributes such as wind direction, chemical properties, type of chemical (killing or selective), and control objects (broadleaf weeds or grass weeds) must be clarified.
Wind speed: The herbicide operation should be carried out in the absence of wind or breeze to reduce the drift of the liquid medicine.
Surrounding crop types: Learn about possible effects of herbicide types on surrounding crops.
