Management of pea powdery mildew

An experiment was conducted to evaluate different bio-agents, biorationals and botanicals to control powdery mildew of pea. During evaluation, all the seven treatments viz. hexaconazole, NSKE, Lantana camara leaf extract, B. subtilis, T. harzianum, cow urine, butter milk were found to be significantly superior over control in managing the powdery mildew disease. Among all treatments, T1 (Hexaconazole 5 EC- 0.05%), T2 (NSKE 5%), T5 (T. harzianum 0.4%), T6 (cow urine 10%), T3 (Lantana camara leaves extract 10%) were significantly superior over other treatments for managing powdery mildew.

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 ecofriendly 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.

Experiments were conducted at Sartingal farm of Regional Horticulture Research Substation (RHRSS) Bhaderwah, Doda, SKUAST-Jammu in randomized block design with eight treatments replicated thrice to assess the losses caused by economically important diseases of pea viz., Ascochyta blight and powdery mildew of pea (Pisum sativum L.). Eight different fungicides and bioagents evaluated as foliar spray, recorded significant reduction against ascochyta blight and powdery mildew disease incidence with a concomitant significant increase in yield over control.

The field experiment was conducted at the Department of Plant Pathology SHUATS during the rabi season, to investigate the “Effect of intercropping on purple blotch (Alternaria porri) of onion (Allium cepa L.)” a legume intercrops evaluated were. Chickpea (Cicer arientinum), pea (Pisum sativum), lentil (Lens esculantum), french bean (Phaseolus vulgaris), cluster bean (Cyamopsis tetragonoloba), the efficacy of the legume intercrops in reducing the foliar disease was compared to a fungicide carbendazim (0.1%).
