Control of ginger storage rot by agrochemicals and biocontrol agent

摘要

Healthy seed rhizome is an essential prerequisite for optimum crop production in ginger. In view of the serious losses noticed during storage of seed rhizomes of ginger due to fungi and infestation by scales and mealy bugs, studies were undertaken todetermine the effectiveness of treatment of seed rhizomes with agrochemicals and biocontrol agents . The present studies revealed that treatment with agrochemicals and biocontrol minimised the storage loss. Treatment with fungicides like Mancozeb and Metalaxyl alone and in combination with insecticides viz., Quinalphos and Malathion and BCA were all on par and showed an increased percentage of recovery of healthy as well as plan table seeds. Increased percentage of germination was also noticed in thesecases. Combination of agrochemicals with biocontrol as integrated measure has been adopted since this would result in carry over of biocontrol inoculum to field when treated rhizomes are planted.
