Agriciltural microbiology| Summary: | Objective. Comparative assessment of vegetable crop varieties by the level of resistance to the main biotic factors in the context of plant protection system, with an emphasis on the implementation of integrated approaches to reduce pesticide load. Methods. The research was based on the example of six genotypes of white cabbage, which were selected for testing in the natural and climatic conditions of the Right-Bank Forest-Steppe of Ukraine. The main biotic factors considered in the research were alternariosis (Alternaria spp.), peronosporosis (Peronospora parasitica), bacteriosis (Xanthomonas campestris), as well as typical phytophages — cabbage scoop (Mamestra brassicae), cabbage moth (Plutella xylostella) and cruciferous flea (Phyllotreta spp.). Resistance was assessed using a five-point damage scale; for general interpretation of the results, descriptive statistical analysis was performed, taking into account the variation of indicators and correlations. The degree of damage was recorded in the phase of technical ripeness, using field observations during two growing seasons (2023–2024). The results are presented in the form of a summary table and two comparative graphs illustrating the variability of varietal resistance to diseases and pests. Results. The most resistant to a complex of biotic factors (phytopathogens and pests) were the varieties Slava 1305 and Amager 611, which showed the lowest scores for both disease and pest damage. Zenon F1 was resistant mainly to bacterial diseases. On the other hand, hybrids Transfer and Parel F1 required additional agrochemical protection due to the high degree of damage. Conclusions. The results obtained indicate the effectiveness of statistical methods in identifying resistant varieties that can be the basis for integrated plant protection, as well as a source of valuable genetic material for further selection program. The use of varieties with hereditary tolerance can theoretically reduce the number of pesticide treatments by up to 30%, by reducing the average damage score by 2–3 points from (4–5 to 1–2), which is consistent with evaluations in studies on integrated plant protection. The use of such approaches is relevant in the strategies of agricultural production adaptation to stressful environmental conditions. |
