Abstract
The present study entitled as "Management of gladiolus wilt by using leaves of allelopathic plants" was carried out during 2018-2019, at Plant Pathology Section, College of Agriculture, Nagpur, with two main treatment viz., Levels of allelopathic M1 (2g leaves/100g soil), M2 (4g leaves/100g soil) and M3 (6g leaves/100g soil) and five allelopathic plants viz., Allium sativum (Garlic clove), Ipomoea carnea (Besharm), Annona innoxia (Sitaphal), Eucalyptus globulus (Eucalyptus) and Azadirachta indica (Neem) were evaluated against Fusarium oxysporum. The test fungus was found pathogenic and resulted 80% wilt in Psittacenus Hybrid. In vivo experiment Azadirachta indica treatment was found significantly superior requires minimum days to emergence of corms (15 days) and minimize the wilt incidence (56.89%) and mortality (11.11%) and also increased shoot length plant-1 (35.10 cm/ plant-1), spike length plant-1 (50.22 cm), number of leaves plant-1 (5.73 number of flower/spike (7.21), number of corm plant-1 (6) and weight of corm (16.04g) over Fusarium. Treatment M3 showed minimum wilt incidence (55.01%) and mortality (22.22%) and maximum shoot length (35.45 cm/ plant-1), spike length plant-1 (49.41 cm), number of leaves plant-1 (5.74), number of flower/spike (6.96), number of corm plant-1 (6.29) and weight of corm (15.87 g/pl) than that of M2 treatment (4g leaves/100g soil) and M1 treatment (2g leaves/100g soil).
Description
It relates to allelopathic plant leaf residues of Azadirachta indica @ 6g leaves/100g of soil can reduce wilt disease, mortality and also enhanced plant growth and quality parameters in gladiolus variety.
Keywords
