...5 to 30 plants m-2). The threshold level of Rumex dentatus was observed in T5 and became worse with further increase in population density of Rumex dentatus. It is concluded that yield and yield related parameters were adversely affected in case of higher infestation of Rumex dentatus as it competes with the major crop for resources and exhibits auto-toxicity when grown in association with wheat crop.

...s concluded that weather thresholds as identified and regression models developed, along with medium range weather forecasts of 5 days available from India Meteorological Department (IMD), could be useful to forewarn aphid 2 days in advance for farmers. To escape critical aphid incidence, rape and mustard crops need to be sown by 15 October, because crops sown beyond this period are likely to be adversely affected by aphid.
