EFFECT OF SOIL SOLARIZATION ON MANGO DECLINE PATHOGEN, LASIODIPLODIA THEOBROMAE
MUHAMMAD ALI KHANZADA1, ABDUL MUBEEN LODHI1,2 AND SALEEM SHAHZAD1*
Abstract: Polyethylene mulching significantly enhanced the soil temperatures in
mulched soils. Soil temperatures were negatively correlated with soil
depths therefore affect of mulching was more profound in upper soil
layer. Soil mulching with polyethylene sheet for 2 weeks in hot summer
was highly effective in reducing soil population densities of
Lasiodipodia theobromae. Significantly less recovery of the fungus
was recorded from straw pieces that were mulched at the depth of 5 cm
for 2 weeks. Similarly, the polyethylene mulching for 15 days at the
depth of 5 cm proved highly effective in reducing the
conidial viability of L. theobromae. Reduction in L.
theobromae inoculum was positively correlated with the duration of
mulching and negatively correlated with soil depth. 1Department of Agriculture And Agribusiness Management, University of Karachi, Karachi-75270, Pakistan. 1,2Department of Plant Pathology, Sindh Agriculture University, Tandojam, Pakistan |
