Grape Diseases

E-mail Print PDF
Presented by Dr. MP Srivastava, initiating Grape Health Clinic, upon request from Maharashtra Grape Grower Association.

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.

Plant Clinic – A technological marvel in plant disease control

E-mail Print PDF
Presented by Dr. M. P. Srivastava, CCS Haryana Agricultural University, Hisar – 125 004, India

Food is the prime requirement of man for which he depends on agriculture. Ever-growing population, more so in developing nations, fast urbanization and industrialization and alarming losses due to plant diseases pose a serious threat to food security. While rising population can be managed or not, plant diseases can be managed to a larger extent. One of the important aspects in the management of plant diseases lies in its correct diagnosis for which well-organized plant clinics are must. Plant clinic’s role does not remain confined to diagnosis but making suitable recommendations. Since plant clinic may not render suitable services particularly in the event of outbreak of epiphytotics hence mobile plant clinics can render better services in reaching diverse areas. May the dawn of this millennium witness plant clinic as global phenomenon. Read more on Plant Health Clinic

Strobilurins- A New Generation fungicide

E-mail Print PDF
Presented by Dr. MP Srivastava (Complete presentation on Strobilurins, available upon request)

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.

Transfer of plant pathology knowledge for rural prosperity – an Asian perspective

E-mail Print PDF
Presented by Dr. MP Srivastava, as a Keynote Address at the 8th International Congress of Plant Pathology, Christchurch, New Zealand, 2 – 7 February 2003

Shrinkage of arable land due to an ever-increasing population and the incidence of disease have become stumbling blocks in improving agricultural production and, consequently rural prosperity. This can be achieved by increasing productivity on one hand and by avoiding losses from diseases and pests on the other. In order to ensure sustainability, we have to aim for judicious pesticide application and also rely upon integrated pest management, biotechnology and organic farming. Establishment of organized plant clinics independently or under an Agricultural Information Technology Centre shall go a long way to identifying the problem and adopting suitable measures on the recommendation of the practitioner or consultant.
