The results of this study can help design management strategies for the control of tomato early blight in Pakistan. In-vivo evaluation, mancozeb, and Neem extract were sprayed on the tomato germplasm lines., The plants that were treated with mancozeb had lower levels of disease, higher chlorophyll contents, the plant height, and the number of fruits were significantly high as compared to neem treated plants and the plants not sprayed with any fungicide or biological compound. Among the plant extracts, the Neem extract inhibited the 78% mycelial growth of pathogen at S/2 concentration (20% water + 80% plant extract) after 7 days.

Abstract: Six isolates of Alternaria solani, the causal agent of tomato early blight, collected from various tomato-growing areas in Serbia, were tested in. Among the fungicides, mancozeb showed the most significant inhibition as compared to other fungicides and inhibited the 90% growth of pathogen at 300 ppm after seven days. Each fungicide and plant extract inhibited the mycelial growth of the pathogen significantly. The fungicides (mancozeb, cabriotop, and difenoconazole) and the plant extract (Neem, Amaltas, and Garlic) were evaluated at different concentrations in vitro for mycelial inhibition evaluated at different intervals of time. Conidia were dark brown and had a cross and longitudinal septa with a long beak at the apex of the conidium. Early blight (EB) caused by Alternaria solani is one of the most important tomato diseases in Kenya and farmers predominantly rely on synthetic fungicides. The pathogen grown on PDA for 5 days produced dark brown mycelium and brown conidiophores bearing conidial chains. One variety was resistant, three varieties were moderately resistant, twelve varieties were moderately susceptible, and four varieties were susceptible. In the present study, the response of twenty tomato germplasm lines was tested against early blight under field conditions. lycopersici is a very devastating disease in tomato fields in Pakistan as well the rest of the world.

To prevent damp conditions that can kickstart blight and keep water droplets from splashing spore-inoculated dirt up onto your plants, you should water the soil directly.
