Dr.W.Larchalex from botanic institute of University Insbruck (Austria) described (in 1958 y.) the guard of plants before frost with bor (spray by borax) in him experimental works. Bor reputedly increase immunity of cytoplasm against frost. The spray by borax is used at the guard of viniculture and too in fruit gardens (guard flowers). The guard against may frost was too certified for tomatoes and peppers.I write how I read.
