e0“using the recommended rate of herbicides, (isoproturon + diflufenican) at 300g a.i./fed. for control total annual weeds, tribenuron-methyl at 6.0g a.i/fed. for control broad-leaved weeds and clodinafop propargyl at 21g a.i./fed for control grassy weeds as applied alone post- emergence as well as hand weeding twice, gave excellent weed control (93.6, 68.0, 45.9 and 93.6 % ), respectively.”

Other claims from this paper (19)
- Intervention effect Recommended-rate tribenuron-methyl gave 68.0% broad-leaved weed control.
- Intervention effect Recommended-rate clodinafop propargyl gave 45.9% grassy weed control.
- Intervention effect Hand weeding twice gave 93.6% weed control.
- Intervention effect Moderate-rate isoproturon plus diflufenican with 1% urea gave about 90.2% annual weed control.
- Intervention effect Moderate-rate tribenuron-methyl with 1% urea gave about 65.9% annual weed control.
- Intervention effect Moderate-rate clodinafop propargyl with 1% urea gave about 44.5% annual weed control.
- Intervention effect Low-rate isoproturon plus diflufenican mixed with urea gave poor control and significantly lower efficiency at the first survey of the first season.
- Intervention effect Low-rate tribenuron-methyl mixed with urea gave poor control and significantly lower efficiency at the first survey of the first season.
- Intervention effect Low-rate clodinafop propargyl mixed with urea gave poor control and significantly lower efficiency at the first survey of the first season.
- Intervention effect High-rate herbicides, moderate-rate herbicides with urea, and hand weeding increased wheat growth and yield components relative to other treatments.
- Intervention effect All herbicides and hand weeding increased grain protein, phosphorus, potassium and carbohydrate percentages and uptake over control.
- Intervention effect All herbicide treatments slightly decreased chlorophyll a, b and total chlorophyll.
- Intervention effect All herbicide treatments increased wheat carotene content.
- Association Fresh biomass of total, grassy and broad-leaved weeds was negatively correlated with wheat yield.
- Observation Grassy weeds were more competitive than broad-leaved weeds against wheat yield and its components.
- Recommendation The authors recommend high-rate isoproturon plus diflufenican alone or moderate rates with urea under heavy annual weed infestation.
- Recommendation The authors recommend high-rate tribenuron-methyl alone or moderate rates with urea against broad-leaved weeds.
- Recommendation The authors recommend high-rate clodinafop propargyl alone or moderate rates with urea against grassy weeds.
- Mechanism The authors conclude that these measures minimize weed competition, maximize weed reduction, and increase wheat yield and components.
