- Control Recommendationsontrol Recommendations (, because
pest species and recommended controls vary regionally.
Recommendations for commercial use and home use are made
separately for specific reasons. Many pesticides used by
commercial growers require applicators to be certified; these
may not legally be purchased or applied by non-certified
applicators. Materials recommended for home fruit production
are safer for application in the typical homeowner
environment.).
