Abstract

Kalmegh is susceptible to various diseases like other crops, which reduce the
yield and quality. Fungicides are applied on crops mainly for protection of plants against
various diseases. Toxic pesticide residues build up in agricultural produce as a result of
frequent, indiscriminate fungicide usage. This fact has casual concern in society to assess
health hazard more accurately. Public health is seriously endangered when pesticide residue
is consumed in food. To maintain the safety of humans and other animals, it is crucial to
research pesticide persistence in crops. In the course of the study on integrated management
of Corynespora leaf spot in Kalmegh under pot conditions, application of Azoxystrobin +
Tebuconazole @ 0.1% at the onset of disease development was found to be most effective,
with 72.03% reduction observed over control. It was found that the residues of Azoxystrobin
11% + Tebuconazole 18.3% – 29.35 SC applied @ 146.5 g ai/ha in Kalmegh leaves reached
LOQ of 0.05 µg/g after 5 days. The waiting period of 9 days can be suggested to be followed
for the safe consumption and processing of Kalmegh leaves following the application of an
approved dose of Azoxystrobin 11% + Tebuconazole 18.3% w/w SC.
