Mite and Woolly Apple Aphid Control

Transcription

1 Mite nd Woolly Apple Aphid Control Some of the pesticides discussed in this presenttion were tested under n experimentl use permit grnted y WSDA. Appliction of pesticide to crop or site tht is not on the lel is violtion of pesticide lw nd my suject the pplictor to civil penlties up to $7,5. In ddition, such n ppliction my lso result in illegl residues tht could suject the crop to seizure or emrgo ction y WSDA nd/or the U.S. Food nd Drug Administrtion. It is your responsiility to check the lel efore using the product to ensure lwful use nd otin ll necessry permits in dvnce Wilur-Ellis 2 Ferury 28 Cmpells, Cheln, WA Elizeth H.
