PRINCIPALS AND PRACTICES OF WEED MANAGEMENT
AGRO 0503 (2-1-0)
Course Objectives
1) To familiarize the students about the weeds, crop -weed competition and critical period.
2) The main objectives of is to let learn the student about the management of weeds with different techniques.
CO - PO Mapping
Cos Course Outcomes Mapping COs with POs
CO1 The students will able to identify different weeds learn the cycle of PO1
weeds and crop weed competition.
CO2 Students will able to get depth knowledge of weed biology, PO1
modification of different plant parts and dispersal mechanism of weed
CO3 The Students will get knowledge about different methods of weed management , PO2
herbicides and their selectivity
Programme Outcomes
PSO1 : Impart knowledge and understanding of fundamental concepts and techniques of maintaining and enhancing soil fertility, crop production, crop management, crop improvement, biodiversity and sustainability of agriculture worldwide.
PSO2 : Develop the ability to know farming practices and their scope to improve in the rural areas and the environments.
PSO3 : Apply knowledge of basic science through Agricultural microbiology, Plant biochemistry and Biotechnology.
PSO4 : Apply knowledge of Agri-business management and finance to develop profitable agricultural system.
Course Syllabus
Theory
UNIT I Weed biology, and ecology and classification, crop-weed competition including allelopathy; principles and methods of weed control and classification management; weed indices, weed shift in different eco-systems
UNIT II Herbicides introduction and history of their development; classification based on chemical, physiological application and selectivity; mode and mechanism of action of herbicides.
UNIT III Herbicide structure - activity relationship; factors affecting the efficiency of herbicides; herbicide formulations, herbicide mixtures, sequential application of herbicides rotation; weed control through use of nano-herbicides and bio-herbicides, myco-herbicides bio- agents, and allelochemicals; movement of herbicides in soil and plant, Degradation of herbicides in soil and plants; herbicide resistance, residue, persistence and management; development of herbicide resistance in weeds and crops and their management, herbicide combination and rotation
UNIT IV Weed management in major crops and cropping systems; alien, invasive and parasitic weeds and their management; weed shifts in cropping systems; aquatic and perennial weed control; weed control in non-crop area.
UNIT V Integrated weed management; recent development in weed management- robotics, use of drones and aeroplanes, organic etc., cost: benefit analysis of weed management.
