The aim of work was to test the antibiotic and phytotoxic activity of cultural filtrates of 125 micromycete strains isolated from different ecological niches. Methods. The activity was studied using different test-organisms-Gram-negative phytopathogenic bacteria, yeasts and green algae. Results. It is shown that 57 cultures were developed biological activities only. The wide spectrum of antibiotic action and middle antifungal activity was characterized for the cultures of genus Aspergillus and Penicillium. A fungistatic activity was shown only by strains as A.

The present studies were conducted in 2013 in three apple orchards differing from each other by the age, the apple varieties and system of chemical control of pests. Their purpose was to monitor codling moth (Cydia pomonella L.) in different types of apple orchards using pheromone traps, finding out the relation between the occurrence of moths and the sum of effective temperatures as well as determining the number of diapausing caterpillars of this species with the use of bands of corrugated paper. The analysis of male flight of codling moth on the basis of pheromone traps makes it possible to state the occurrence of three generations. Increase of average annual temperature is directly influence on generation number of codling moth in Ukraine.

Бур'яни, погіршуючи умови росту і розвитку культурних рослин, завдають великої шкоди сільському господарству України. Одним із методів біологічного методу боротьби з бур'янами є застосування біогенних препаратів-продуктів біосинтезу мікроскопічних грибів або препаратів на основі живих мікроорганізмів. Метою роботи був скринінг на фітотоксичну активність 82 штамів мікроміцетів родів Penicillium,
