تقييم بعض أساليب التكامل في اختزال الإصابة بفايروس تجعد و اصفرار أوراق الطماطة Begomovirus Tomato Yellow Leaf Curl Virus

Abstract EN

Some of factor of bioresistance on the sorts processed by bioformulation, were assessed, and some of the chemical treatments and they are exterminatory mospilansp, growth organizations Gibberellin, highly-phosphor manure (Amino alexin) in induced the rate of infection by virus (TYLCV) and pathogen effects caused by it represented in shortage of the amount of chlorophyll, leaf area amount , plants length and its weights and the resulting as well as the degree of infection.

The symptoms of infection in virus (TYLCV) were standardized and on this basis, the degree of infection was measured the efficiency of the processing of plants by bio formulation (Bio green) was evaluated in motivating the systemic resistance in tomato plants against virus infection (TYLCV) after planting by watering plants in the stage real leave 2-3 to determine the ability of bacteria in improving plant growth and its effect on the degree of infection.

The function of three sorts (GS, surah, Noor) of tomato plants against the reduction of the degree of infection by virus, the standards of plant growth and the indications of virus in these sorts.

The results of interrelations between treatments and sorts showed the existence of obvious differences in the features of growth and the indications of the effect of virus tomato sorts, where the processing of bio formulation Bio green and Applaud with the sorts Noor were successful and the minimum rate in the degree of infection was given where it reached (34.50) followed by and in great difference the treatment in the bio formulation and the sorts Noor where it reach (40.29), where the treatment of Mospilan with the sorts GS gave the maximum in the rate of infection reached (53.12).As for the rate of chlorophyll, the bio formulation with Applaud and the sorts Surah overcomesandreach(41.97).

) followed and by great difference the treatment of bio formulation and applaud with the sorts GS reached (39.81) where the treatment of phosphor-highly manure gave the minimum rate in the chlorophyll which reached (27.72) .As for the effect of virus in leaf space, the treatment of bio formulation with Applaud and the sort Noor gave maximum rate in the leaf space reached (42.52)cm2 then, and with great difference , followed by the treatment of the showed sort Noor with Gibberellin which reached (41.35)cm2 while the treatment of mospilan with the sort GS gave the minimum rate in the overage of leaf space reached (20.22) cm2.
