Abstract:

Pea powdery mildew is an air-borne disease of worldwide distribution. It is particularly damaging in late sowings or in late maturing varieties. It is caused by Erysiphe pisi. In order to bring residue free peas, there is need to manage these diseases through eco-friendly measures such as by using the chitosan which is antifungal as well as induces resistance in plants. GI chitosan is a deacetylated derivative of chitin obtained by gamma irradiation of chitosan. GI chitosan at concentrations @50 and 75 ppm was evaluated in the control of Erysiphe pisi. Leaves were sprayed with GI chitosan twice at 30 and 40 DAS.The best treatment was sprayings of GI chitosan @ 75 ppm at 30 and 40 DAS which recorded 11.88 and 7.18 per cent disease intensity and 52.34 and 79.06 per cent disease control, respectively and it was at par with recommended wettable sulphur fungicide treatment. The results indicated that there was highest yield in the treatments of GI chitosan @75 ppm at 30 and 40 DAS was30.49q ha-1 as compared to control i.e.13.84 q ha-1. Depending on the concentration used, GI chitosan reduced development of powdery mildew from 52.34% to 79.06% and its effectiveness was similar to wettable sulphur at concentration 0.2% (standard). Efficacy of chitosan increased with increasing of its concentration. Thus, preventive sprays of GI chitosan reduce the powdery mildew intensity in pea.
