The use of biotic agents, such as mammalian, avian and piscine herbivores, phytophagous insects, mites, nematodes and plant fungal diseases, to control weeds is based on the fact that these plant-attacking organisms can reduce their host plant populations to non-noxious levels of abundance, or can be manipulated in such a way as to do by: Makepeace R J ().

These include the increased use of conservation-tillage 5/5(2). Weeds are generally classified into two groups, ‘grass weeds’ and ‘broadleaved weeds’. Owing to their similarity to cereals in both biology and life cycle, grass weeds are the most economically significant and hardest to control weeds.

Weed Resea – Introduction The increase in organic farming resulting from the European publics concern regarding pesticide use in farming has created more interest among farmers in physical weed control, including weed harrowing (Bond.A field study was conducted from to to compare weed population and growth dynamics with three irrigation systems: (1) a conventional water-seeded control system (WS-Control), with a permanent flood of 10 to 15 cm from planting until 1 mo prior to harvest; (2) a water-seeded alternate wet and dry system (WS-AWD), with the field flooded.
