Screening Of Selected Fungal Collection For Resistance
Glyphosate is a non-selective broad-spectrum herbicide that commonly been used in the agricultural system to controls the weed populations but also affects microbial populations especially fungi in soil. Plants that were infected by plant pathogenic fungi may affect the crop quality and yield quan...

all types of fungi are susceptible towards glyphosate because certain types of fungi have different physiological
response towards glyphosate. For instance, there are some fungi are resistance towards glyphosate due to the
