PeaPowderyMildew Treatment: ControllingPowderyMildewInPeas.Powderymildewinpeas often develops quickly when days are warm and dry, but nights are chilly with dewy mornings. Poorly drained soil and restricted air circulation also contribute to development of the disease. the chemical and biological methods of controllingpowderymildew, examine the natural. resistance to powderymildewin the important crop legumes, especially in the garden pea. (Pisum sativum L.) as the main and best-studied example of natural mlo1-based recessively. The present study investigated the resistance phenotype, inheritance, and genomic location of gene(s) controlling resistance to powderymildewinpea genotype ‘JI2480’. The powderymildew resistance in ‘JI2480’ appeared to be a spatial phenomenon showing expression only in leaf tissues. How to Prevent and ControlPowderyMildew. powderymildew plant disease on a yellow summer squash plant and leaves. Powderymildews create a white coating on leaves and stems. Find out how to manage this common fungal disease effectively. Results indicate that flusilazole at 0.1% is highly effective, considerably reducing disease intensity and increasing yield compared to untreated controls. This suggests that flusilazole could be a key component in integrated disease management strategies for powderymildewinpeas. This review examines the methods of controllingpowderymildew that are used in modern practice, including fungicides and biological agents. Special attention is paid to the plant genetic mechanisms of resistance, which are the most durable, universal and environmentally friendly. In this contribution we review the state of the art for genetic resistance to powderymildew, caused by Erysiphe pisi, inpea (Pisum sativum L.) and potential use of marker-assisted selection (MAS) for developing disease resistant cultivars. Powderymildew of pea, caused by Erysiphe pisi DC, is one of the most devastating diseases, causing up to 50% yield losses globally.Single recessive gene controlspowderymildew resistance inpea. International Journal Vegetable Science. We collected peapowderymildew diseased leaves from ten growing villages in the Nilgiris ecosystem to study the phenotypic and genotypic characteristics of the peapowderymildew pathogen. Powderymildew is particularly damaging in late sowings or in late maturing varieties. The earlier the disease occurs the more severe the damage Powderymildew affects all green parts of pea plants. Powderymildew (caused by Erysiphe pisi var. pisi DC.) resistance of field pea (Pisum sativum L.) cultivars is dominated by the single gene er1. Monoculture of the er1 gene may encourage pathogen evolution for more virulent race(s) and breakdown of the resistance. Powderymildewinpeas is caused by Erysiphe pisi DC, and is a serious disease that can cause yield losses of 25–50% (Warkentin et al., 1996; Tiwari et al., 1997; Fondevilla and Rubiales, 2012). Eleven advanced lines/cultivars of pea were tested for yield and resistance against powderymildew under natural conditions of infection. All the lines were found to be resistant while the local cultivars (Climax and PF-400) proved highly susceptible.
