Aim. Studying of the influence avermectin-containing polyfunctional preparations Avercom and Nova on enhancement resistance to fusarium wilt tomato plants in vitro. Methods. Tomato were cultivated vitro for 30 days presence 25 μl/l Nova. Analysis was carried out by spraying with a conidia suspension Fusarium oxysporum f. sp. lycopersici F. solani. Resistance has been evaluated 15 after inoculat...

Anthelmintic resistance (AR) is a serious problem for the control of equine gastrointestinal nematodes, particularly in the cyathostomins. The fecal egg count reduction test (FECRT) is the most common method for diagnosing AR and serves as the practical gold standard. However, accurate quantification of resistance and especially accurate diagnosis of emerging resistance to avermectin/milbemycin...

The avermectins are a complex of chemically related agents which exhibit extraordinarily potent anthelmintic activity. They are produced by a novel species of actinomycete, NRRL 8165, which we have named Streptomyces avermitilis. The morphological and cultural characteristics which differentiate the producing organism from other species are described. The avermectins have been identified as a s...

Avermectins and milbemycins are commonly used in agro-ecosystems for the control of parasites in domestic livestock. As integral members of agro-ecosystems with importance in maintaining pasture health through dung burial behaviour, dung beetles are an excellent nontarget bio-indicator taxon for examining potential detrimental effects of pesticide application. The current review focuses on the ...
