Fungicides are important tools for managing diseases in many crops. Unlike insecticides and some herbicides which kill established insects or weeds, fungicides are most commonly applied to protect healthy plants from infection. To be effective, fungicides must be applied before infections become established and in a sufficient spray volume to achieve thorough coverage of the plant or treated ar...

Letters toxicity, no antidiphtheria serum was administered. The patient became well and was discharged on day 4. In the first case, a throat culture could not be done because the patient had already received local antiseptic paint. However, the diagnosis was clinically consistent with classic diphtheria with features of toxicity. In the second case, diphtheria was suspected only after bacteriol...

Bakanae disease is an emerging problem of Basmati rice (Oryza sativa L.) in India and most the basmati varieties are susceptible to this disease. Present study was carried out evaluate identify effective fungicide against bakanae for which 12 fungicides (single combination) were evaluated as seedling treatments during rainy (kharif) season year 2019 2020. Minimum incidence observed with Carbend...

The chemical management of the black leaf streak disease in banana caused by Mycosphaerella fijiensis (Morelet) requires numerous applications of fungicides per year. However this has led to fungicide resistance in the field. The present study evaluated the activities of six fungicides against the mycelial growth by determination of EC50 values of strains collected from fields with different fu...

Evaluation of various fungicides against leaf blast of rice was carried out at Agricultural Research Station, Bavikere, Tarikere (Tq), Chikkmangalore (Dist.), Karnataka during kharif 2010 and 2011 season. A highly susceptible rice variety TO-39 was planted in Randomized Complete Block Design and the application of various fungicides viz Dithane Z -78 75 WP (0.2 %),Carbendazim(0.1%), Propiconazo...

Trichoderma isolates were obtained from diseased leaves and fruit collected from plantations in the main banana production area in Northern Queensland. Phylogenetic analyses identified the Trichoderma isolates as T. harzianum and T. virens. The Trichoderma spp. were found to be antagonistic against the banana leaf pathogens Mycosphaerella musicola, Cordana musae, and Deightoniella torulosa in v...

The purpose of this investigation was to evaluate the possible influence of a mixture of pesticides on medium-term carcinogenesis using improved hepatocarcinogenesis protocols. We performed a 12 commercially available pesticides combination with alachlor, atrazine, carbofuran, chlorpyrifos, diazinon, dicofol, endosulfan, iprodione, mancozeb, maneb, procymidone and rotenone. The mixture was give...
