REDUCTION IN RUSSETING OF GOLDEN DELICIOUS
Rain, high humidity, and fluctuations in temperature during early fruit development may cause Golden Delicious fruit to russet. If severe, this russeting may lower fruit grade. Gibberellins A4+7 application, sold as Provide, will reduce skin russeting that is caused by environmental factors early in the season.
Concentration and timing: Apply 2-4 applications of 15-20 ppm Provide (10-13 ozs./100 gals.) starting at petal fall and continuing at 7 to 10 day intervals. The early applications are most important.
Special considerations:
• Do not apply over 100 gallons of spray per acre.
• Do not use a surfactant or a spreader-sticker because they may increase russeting.
• Do not apply more than a total of 40 ozs./acre because return bloom may be reduced.
• The restricted entry interval is 12 hours, possibly longer.
