Efficacy of Pseudomonas spp. in control of apple powdery mildew

Abstract

The results of Pseudomonas spp.’s effect on Podosphoera leucotricha (Ell. et Ev.) (Salm.) in commercial plantings of apple trees of Renet Simirenko variety are presented in the article. It reveals that use of the bio-fungicide in three consistent treatments during fruit ripening period at the rate of 4.0 l/ha reduces the disease’ spread and development intensity, ensuring biological efficacy of 94.4-99.6%.
