Evaluation of Different Fungicides Against Alternaria Leaf Blight of Tomato (Alternaria solani)

Evaluation of different fungicides in the control of purple blotch [Alternaria porri (Ellis) Cif] of onion

“…Azadirachta indica (Neem leaf extract) was found least effective at all concentrations against Alternaria porri. Similar results were observed by Vijaya and Rahman (2004) [12] , Madhavi et al, (2012) [8] , Kumar et al, (2017) [7] , Roopa et al, (2014) [11] and Jakatimath et al, (2017) [5] . Eight different fungicides were evaluated for management of purple blotch of onion by seedling treatment at the time of transplanting with two spray of same fungicide after 45 and 60 days, respectively, under artificial inoculated field conditions.…”

Crude Citric Acid of Trichoderma asperellum: Tomato Growth Promotor and Suppressor of Fusarium oxysporum f. sp. lycopersici

“…Variation in antagonistic mechanisms has been proposed, including direct and/or indirect mechanisms. Direct mechanisms include microbial competition for space and/or nutrients, antibiosis, and mycoparasitism, while indirect mechanisms include induction of defense responses in the host plant and/or plant growth enhancement to increase yields [ 11 ]. Moreover, Trichoderma spp.…”

Effect of Some Fungicides against Early Blight of Tomato (Lycopersicon esculentum Mill.) Caused by Alternaria solani (Ell. & Mart.) Jones and Grout and their Impact on Yield

“…The disease, if favoured by high temperature and humidity (crowded plantation, high rainfall and extended period of leaf wetness from dew) and plants are more susceptible to the blight infection during fruiting period (Momel and Pemezny, 2006). Fungicides and botanicals application can increase the genetic potential and yield reduction due to disease can be minimized (Patel and Choudhary, 2010;Chourasiya et al 2013;Kumar et al, 2017). Preventive fungicides and botanicals inhibit the spore germination and penetration but pathogen can derive resistance against fungicide application so repeated application of fungicides at proper dose and interval of time is mandatory (Hossain and Hossain, 2009;Kumara et al, 2010).…”
