Spray reduces crackin: Think of it as an insurance policy, urges inventor Dr. Larry schrader

摘要

A new wax product that is sprayed on trees to prevent rain cracking can reduce losses by half, says the Washington State University Iresearcher who invented it. But to be effective, it must be applied weekly during the month before harvest. Dr. LarrySchrader, horticulturist at WSU's Tree Fruit Research and Extension Center in Wenatchee, said that the product, which is called RainGard, can't just be applied when the weather forecast predicts rain.
