Entomofauna of hazel (Corylus avellana L.) under additional protection with bio-products

Abstract

Conventional crop cultivation based on chemical plant protection products and synthetic fertilizers creates an apparent image of effective protection. Irrational usage of chemical products in horticulture production, with an aim at increasing yields results in a decrease of fruit quality and leads to degradation of the environment. Mandatory application of the principles of integrated plant protection, which became effective on 1st January 2014, has forced the combined usage of chemical, biological and physical methods. The aim of our study was to assess the effect of an application of additional plant protection with bi-products such as EmFarma, Polyversum WP on the occurrence of entomofauna on hazel plants (Corylus avellana L.). The study has demonstrated that aphids, with the dominant species Myzocallis coryli Goe. were a potentially dangerous pest of hazel plantations. It was also determined that the product Polyversum WP stimulates more abundant occurrence of Carabidae and phytophagous species inhabiting hazel leaves. Moreover, due to less numerous presence of phytophages, hazel aphid in particular, it is recommended to perform an additional plant protective treatment with the probiotics EmFarma Plus and EmFarma 5.

Analysis of the potential of effective microorganisms in plant production

“…They can help improve soil structure and fertility by dissolving compounds unavailable to plants. EM improve the physicochemical properties of the soil, break down organic matter and synthesise nutrients needed for plant development (Ludwiczak et al, 2018).…”
