Yucca Extract: Yucca extract not only makes sprays stick to crop foliage, it is also a great foliar material itself. It contains complex sugar structures which help plants assimilate nutrients, and develop stress resistance. Use two to three ounces per acre or one-fourth teaspoon per gallon per foliar application, when Therm X70 is applied alone or in combination with other foliar materials. Use a maximum of eight to ten ounces per acre per year. This product foams heavily and should be added last when mixed in high agitation systems. Use at sixteen ounces per acre, once a year. Available from Peaceful Valley Farm Supply.
