Abstract: Tukra is one of the major problem in mulberry growing areas and it is caused by pink mealy bug Maconellicoccus hirsutus which affect both the quality and yield of mulberry leaf. In general the tukra- diseased leaves showed high moisture content compared to normal healthy leaves. A preliminary attempt has been made to know the effect of plant extracts of natural pesticide origin on moisture content, loss and retention capacity of tukra affected mulberry leaves. The seed kernel and leaf extracts of Azadirachta indica, Pongamia pinnata, Madhuca longifolia and only leaf extracts of Lantana camara, Adathoda vasica were directly used as a foliar spray on M-5 mulberry variety under field conditions. The results revealed that the tukra affected leaves showed high moisture content (75.92%) compared to normal healthy leaves (71.32%). The moisture content was more in NSKE @ 4% (73.83%) PSKE @ 4% (73.80%), MSKE @ 4% (73.30%), and lowest was recorded from MSKE @ 2% (71.76%) followed by control (70.66%). The maximum moisture retention capacity in infested leaves of tukra was observed in NSKE @ 4% (80.60%) sprayed leaves and lowest was recorded from PLE @ 8% (78.46%) compare to control (77.80%). The minimum and maximum moisture loss of 26.06 and 28.20 % was observed in NSKE @ 4% and MSKE @ 2% respectively over the control (29.23%). There was no significant difference among the different treatments with respect to moisture content, loss and retention capacity of tukra affected mulberry leaves.
