Effective control of weeds is critical for maximising moisture storage and crop yields, reducing the weed seed bank and meeting quality standards at harvest. Crop weeds can most effectively be managed by integrating chemical and non-chemical control, and paying attention to key weed management principles.
Factors to consider when using herbicides, including water quality, general toxicity and spay drift.
