Important findings

Severely infested plot with soil borne pathogens causing nursery, root rot and root knot was selected for developing the IDM package for management of soil borne pathogens including nematodes from contaminated soils to raise healthy new mulberry plantation.

Different treatments in various combinations such as deep digging, soil solarization, application of neem oil cake and growing of Dhaincha crop were imposed. Pathogen population was assessed at 15-20 days interval after the treatment.

After 80 days, complete suppression of pathogen population was recorded in treatments where deep digging (30 cm) along with application of neem oil cake (@ 800 kg/ha after 45 days) and rising of Dhaincha (@ 20 kg seeds/ ha after 6 days) were made. To validate the test results, fresh cuttings were planted in the same treated plots.  All plants were survived in this treatment and were free from soil borne nematodes and fungal pathogens. In this treatment, the plant height and leaf yield were increased up to 32.0 and 35.0 %, respectively over the check.

Recommendations: For taking up the new plantations of mulberry, deep digging/ ploughing the plot up to 30 cm, and after 30 days apply neem oil cake @ 800 kg/ha. 6 days after neem oil cake application, raise Dhaincha crop by sowing the seeds @ 20 kg /ha. And after 40 days mulch the Dhaincha crop in soil before flowering.
