Plant Pathology

 

INTRODUCTION

Welcome to the Department of Plant Pathology. One of our assets is the ability to provide students top-ranked educational and research opportunities in a collegial and friendly atmosphere. Our Goals are to offer superior education in plant pathology and plant-microbe interactions and to broaden the perspectives of plant biology in undergraduate and public education. Our research goal is to understand microbes, plants, and their interactions in the environment in order to provide effective approaches by which plant diseases can be controlled and beneficial interactions can be maximized. Our extension and outreach goals are to integrate and extend knowledge.

OBJECTIVES

The mandate of the Department of Plant Pathology is to engage in quality research, education, and outreach in plant pathology with emphasis on the understanding of relationships among microbes, their hosts, and the environment, and on the management of diseases and other threats impacting agricultural and natural ecosystems, food safety, and human and environmental health with following objectives;
• To teach the subject Plant Pathology to the undergraduate and polytechnic students
• To conduct research on diagnosis and management of crop diseases

Recommendations
1. Management of leaf reddening of Bt cotton
“Application of two sprays of DAP (2%) at 15 days interval during boll development stage in addition to recommended dose of FYM (10 tone) and inorganic fertilizers (125:63:63 kg NPK/ha) is recommended for the management of leaf reddening of Bt cotton grown under Summer irrigated condition of Western Maharashtra.”
2. Management of Para wilt of Bt cotton
“To avoid the para wilt incidence under summer irrigated conditions, the sowing of Bt cotton be undertaken from 2nd fortnight of May to first week of June with 8-15 days irrigation interval.”
3. Disease development in relation to weather parameters
“The following equation representing the relationship between Alternaria leaf blight incidence on cotton and the weather parameters (Tmin, RH-I and RF) is recommended for use in predicting forewarning model in scarcity zone of Maharashtra.”
PDI= - 59.67 – 2.58 x Tmin + 1.31 x RH-I + 0.15 x RF
4. The farmers of middle Gujarat Agro-climatic zone growing paddy variety GR-11 are advised to transplant seedlings during 2nd to 4th week of July with application of 80 kg N/ha (32 kg as basal dose, 32 kg at tillering stage and 16 kg at one week before panicle initiation stage) to reduce the intensity of diseases (bacterial leaf blight and sheath rot) and infestation of insects (leaf hopper, leaf folder and rice stem borer).
5. In middle Gujarat (Agro-climatic zone – III), higher male moth catches of Spodoptera litura, Helicoverpa armigera and Scirpophaga incertulas found during July to December; September to December and August to October, respectively with peak in the month of October by using pheromone trap.
