![]() Haven applied five times had the best yields, with 22.2% higher tons per acre above the untreated and 31.7% better yields than the kaolin clay standard.Ģ016 trials conducted by Helena Research and Development in Biggs, CA: Haven applied four or five times, starting at early nut set, resulted in 11.3% to 17.0% yield increase in tons per acre outperforming the kaolin standard. Four applications of Haven yielded more than the kaolin standard by 13.9% in tons per acre. In 2015, trials of an earlier formulation in Upper Lake, CA of the same active ingredient also showed an increase in both size and number of nuts.Ģ017 trials on walnuts conducted in Upper Lake, CA by Attaway Research: Haven applied at full bloom and then with an additional three applications yielded more than the untreated by 5.7% in tons per acre. Haven treated almonds experienced a 17.4% increase in tons per acre over the untreated plots and a significant 20% increase in tons per acre higher than the kaolin clay standard. In pounds per tree, Haven was 14.2% higher than the untreated and 16.5% higher than the kaolin clay standard.Ģ016 trials on almonds conducted in Arbuckle, CA by Attaway Research: Haven applied three times (0.6% v/v) increased yields above the untreated trees and above the kaolin clay standard. Haven also increased yields of corn and wheat and turf grass.Ģ017 trials on almonds conducted in Arbuckle, California by Attaway Research: Haven applied three times resulted in a 13.9% higher yield (tons per acre) than the untreated trees and a yield 16.3% higher than the kaolin standard. ![]() When two to five applications are sprayed on crops generally starting at bloom, shortly after bloom or at early fruit/nut set, Haven has shown to reduce sun damage and increase yields for certain apple varieties, almonds, walnuts, soft berries, citrus, grapes, and tomatoes. Use of Haven helps treated plants maintain lower leaf temperatures and reduces heat stress on the crops, resulting in higher yields and quality. The active ingredient in Haven is a food-use approved extract derived from coconuts. There are more than 1 million bearing acres of almonds and an estimated 335,000 bearing acres of walnuts 3. Furthermore, if any of the sunburned nuts are rejected rather than downgraded, growers potentially will experience total monetary loss for damaged crops. Sun damaged walnuts result in downgraded status by nut processors and can result in losses of $0.10 to $0.12 per pound for growers (which is the difference between class 1 class 2 in quality) 2. Sun damage in walnuts darkens and shrivels one side of the shell and kernel 1. Walnuts are particularly susceptible to sun damage. In addition, trials in California over the last two years show that Haven applications resulted in significantly higher almond and walnut yields, compared to competing products.īoth almonds and walnuts can suffer yield loss from sun damage. (NASDAQ: MBII) (MBI), a leading provider of bio-based pest management and plant health products for agriculture, turf and ornamental and water treatment markets, announced that the California Department of Food and Agriculture has approved the use of Haven®.
