Fungicidal compositions for agricultural and horticultural use are provided which contain as an active ingredient thereof the antibiotics angustmycin A or angustmycin C. They exhibit excellent protective effects against attack by plant disease fungi or bacteria, have no phytotoxicity and cause no pollution in the environment. A method for protecting plants by the use thereof is also provided.

Fungicidal and bactericidal compositions and method for protecting

Alpha-amylases which have optimum activity between pH 6.5 to 8 and between pH 9.0 to 11.5 at 40.degree. C are produced by culturing strains of Bacillus subtilis on a nutrient medium under aerobic conditions. Some of the alpha amylases are effective in hot and alkaline detergent solutions containing chelating agents.

Alpha-amylases from Bacillus subtilis

N-Higher aliphatic amino acids, lowe-alkyl esters thereof and their salts are useful for controlling numerous plant diseases. They exhibit excellent protective effect rather than curative effect and have no phytotoxicity, extremely low mammalian toxicity and cause no risk of pollution toward soils.
