Pea powdery mildew

The influence of environmental factors on the development of pea powdery mildew (Erysiphe pisi) was studied under field conditions. Epidemiological studies revealed that the apparent rate of disease development was high during 50% flowering to pod initiation stage. Powdery mildew severity showed positively and significantly correlated with maximum temperature and sunshine hours. The correlation was non-significant with minimum temperature and relative humidity.

Powdery mildew and Rust are major diseases of pea of worldwide distribution. Powdery mildew and Rust is an airborne disease. Powdery mildew is a particularly damaging in late sowing or in late maturity varieties. It is caused by Erysisphe pisi. The disease can cause 20-50% yield losses, reducing total yield biomass, number of pods per plant, number of seeds per pod, plant height and number of nodes. The disease also affects green pea quality. Pea rust is characterized by the appearance of two types of symptoms.

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.

Powdery mildew (PM) is an important disease of pea that reduce yield. Ascophyllum nodosum extract (ANE) and chitosan (CHT) are biostimulants used to improve plant health. Efficacy of ANE and CHT was assessed individually and in combination against pea 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.

Powdery mildew of pea caused by Erysiphe polygoni has emerged as a constraint in its cultivation in Rajasthan. Disease appeared in first week of January and reaches its peak in March. Powdery mildew disease is easily detected by the presence of white floury patches appearing on both sides of the leaves as well as tendril stem, pods etc. In extreme severe conditions it causes significant losses in quantity as well as quality of seed.

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%).
