摘要

The reniform nematode, Rotylenchulus reniformis attacks a wide range of crops including sunflower, Helianthus annuus in Egypt as well as in many parts of the world. Elimination of the nematodes has received attention to minimize damage to plants. Thus, the present study aims to estimate the probable effects of three rates of some biofertilizers, plant nutrients and a biocide on the development of R. reniformis in sunflower and growth of the plant. Three Egyptian of bio-fertilizers (BF), i.e. Nitrobien (at doses 0.034, 0.068 and 0.136), Rizobactrein (at doses 0.017, 0.034 and 0.068) and Blue-green (at doses 0.2, 0.4 and 0.8); and three Egyptian plant nutrients (PN) i.e. Citrein (at doses 0.1, 0.2 and 0.4), Kotangein (at doses 0.01, 0.02 and 0.03) and Kapronite (at doses 1.0, 2.0 and 4.0) as well as the biocide Nemaless (at doses 0.005, 0.01 and 0.02) were evaluated as a lower rate, the recommend rate and a higher rate; respectively for control of R. reniformis and improvement of sunflower cv. Giza 101 under greenhouse conditions 30 ± 5 oC. All the evaluated compounds significantly reduced (P≤ 0.05 and/ or 0.01) the number of juveniles in soil, swollen females and egg-laying females on roots. The reduction varied greatly according to the type of experimented products and rate of application. The highest reduction in the nematode populations, swollen females and egg-laying females was attained with seed coating by Rizobactrein followed by Nitrobien as bio-fertilizers while, the least reductions were obtained by using Blue-green as alga biofertilizer followed by Nemaless as a biocide. Application of the plant nutrients, Kotangein as seed coating and Kapronite as soil amendment were effectively decreased the development of the nematode stages. Citrein as a foliar spray nutrient was the least effective. Generally, Rizobactrein and Nitrobien as biofertilizers; Kapronite and Kotangein as plant nutrients proved to be the most effective for controlling R. reniformis and gave the greatest growth of sunflower plants as compared with the rest treatments.
