A Note on Pesticide Use:
Before using an insecticide or fungicide, carefully read the label and note the pre-harvest interval. It is also important to consider the following points:
- Is the chosen pesticide acceptable to your buyers?
- Is the chosen pesticide registered for the intended use?
- Are you using the pesticide as part of an integrated pest management strategy?
- Have all relevant cultural management practices for the pest or disease in question been considered?
- Are you using resistance management strategies, such as alternating fungicides or insecticides having different modes of action (group numbers) to avoid resistance?
Be cautious and accurate when using pesticides. Use proper equipment, maintained in good condition and calibrated accurately. For more information on pesticides and pesticide safety, please refer to the Pesticide Wise section of this website.
