More about screen duo™
Screen™ Duo is an effective solution for reducing losses from sunburn and heat stress in crops.
Sunburnt fruit due to excess heat and light can reduce saleable yields by up to 50 percent, and average losses in some varieties are in the 20 percent range.
With Screen Duo’s innovative technology, growers can:
• Reduce flower abortion
• Maintain fruit set
• Increase yield of red tomatoes
• Increase Brix
• Provide more uniform ripening
Treatment can also improve crop water status
By reducing canopy temperature, the amount of water used for cooling by evapotranspiration is reduced. See Water Savings for details on recent test results.
Application and Timing
Depending on application timing Screen Duo provides multiple benefits.
• Late applications at canopy collapse protect fruit from excess heat and
light, reducing loss due to sunburn by 50 percent or more
• Low rate (5-10 kg/ha) application beginning at flowering provides
improvements including reduction in flower abortion, fruit drop and
• Season-long application at 5-10 kg/ha (lbs/A), beginning just prior to
crop flowering requires continued applications to maintain a visible film
on plants (about every 7 to 10 days).
For sunburn reduction:
Apply product at 50 kg/ha when fruit is half to two-thirds the final size, and repeat application at 35 kg/h to maintain coverage of expanding fruit, approximately every 14 days.
Apply in sufficient volume to provide complete coverage, but not to runoff.
