Abstract
Early blight, caused by Aiternaria solani, is a major foliar disease of potato, severely affecting yield and quality. Afield trial was conducted during 2024–25 at ANDUAT Kumarganj, Ayodhya to evaluate the effectiveness of chemical fungicides, biocontrol agents (Trichoderma harzianum, Pseudomonas fluorescens) and botanical extracts (Tulsi, Neem seed kernel) against early blight in Eastern Uttar Pradesh conditions. The results revealed that chlorothalonil 75% WP @ 0.2% (T3) was found most effective in minimizing disease incidence (14.3%), disease intensity (6.7%) at 75 DAS and reduced disease up to 58.3 and 72.2%, respectively, over control, with the highest tuber yield (323.33 q ha-1), followed by the combination of mancozeb and hexaconazole (299.72 q ha-1). Biological treatments showed moderate efficacy, while botanical treatments were lesser effective. The study highlights the potential of integrating fungicides, bioagents and botanicals, for sustainable and practical solution for management of early blight of potato in Eastern Uttar Pradesh of India.
Early blight ( Alternaria solani) is one of the most common and devastating diseases of potato caused by the fungus. The purpose of this study was to evaluate the efficacy of six selective chemical fungicides against early blight disease of potato. The experimental design was a Randomized Complete Block Design (RCBD) w...

The tomato (Lycopersicon esculentum Mill.) is cultivated in different parts of Ethiopia in the field as well as in the glasshouse for consumption and processing. Helicoverpa armigera, Tuta absoluta and Liriomyza spp. are damaging insect pests, specifically the tomato crop. In the present study, the laboratory and glass...
Sucking insect pests are important constraints to cauliflower production and can adversely affect plant growth and yield when their populations remain uncontrolled. The present study was conducted to evaluate the efficacy of selected botanical biopesticides against major sucking insect pests of cauliflower under field...

Pearl millet [Pennisetum glaucum (L.) R. Br.], commonly referred as bajra, is a crucial cereal food and
fodder crop. It is the most extensively cultivated drought-tolerant, warm-season coarse grain crop. This crop
is susceptible to numerous diseases, among them downy mildew caused by Sclerospora graminicola is the
most...
