Synergism between soil and leaf plant protection products in greenhouse cucumbers and their effect on yield and phytosanitary status
Keywords:
root rot, powdery mildew, effectiveness, yieldAbstract
It was studied the effect of chemical and biological plant protection products (PPP) on root rot (Fusarium and Verticilium root rot) and powdery mildew in cucumber variety Mirey F1 grown in cultivation facilities in the Maritsa Vegetable Crops Research Institute, Plovdiv during the period 2008-2010. The presence and absence of synergism in their action and an influence on the plant productivity was also studied. It was established a high effectiveness against root rot caused by Fusarium spp. and Pythium spp., in treatment of plants with Previcur 607 SL + Topsin М 70 WP and Trichodermin NPA. The last product results in yield increase with 12.09%. A synergism in the action of studied soil and leaf PPP was established. The highest effectiveness against powdery mildew was recorded in soil treatment with Previcur 607 SL + Topsin М 70 WP and leaf PPP Collis, Quadris 25 SC, Timorex 66 EC and Timorex gold.
