Evening Session on Plant Health Clinic - ICPP 2008, Turin (Italy)
Professor MP Srivastava organized the plant health clinic session which was aimed at bringing awareness on the role and need of plant clinics in keeping diseases and pests at bay. Out of 11 listed speakers, 9 of them presented their papers. The session began with the presentation by Prof. Srivastava, who gave an overview of plant health clinics across the globe. In his introductory remarks, he emphasized that although plant clinics are operating in India, the USA, Canada, the UK and Afro-Asian countries, we don’t yet have organized plant clinics like the ones for humans and animals.

Grape is attacked by a number of diseases. However, anthracnose, downy mildew, powdery mildew, and bunch rot/ berry rot caused by certain fungi or group of fungi are most important. Their control lies in modifying vine microclimate; timely annual pruning of dead arms/vines, and also removal of abnormal un-harvested bunches from the vines immediately after harvest is over, and timely and judicious application of fungicides, after annual pruning and during the season.

Strobilurins are a group of chemical compounds used in agriculture as fungicides. They are part of the larger group of QoI inhibitors, which act to inhibit the respiratory chain at the level of Complex III.
Some common Strobilurins are azoxystrobin, kresoxim-methyl, picoxystrobin, fluoxastrobin, oryzastrobin, dimoxystrobin, pyraclostrobin and trifloxystrobin.
Strobilurins represented a major development in fungus-based fungicides. They were extracted from the fungus Strobilurus tenacellus. They have a suppressive effect on other fungi, reducing competition for nutrients; they inhibit electron transfer in mitochondria, disrupting energy metabolism and preventing growth of the target fungi.
