e0“the same herbicides when applied at moderate rate (isoproturon + diflufenican) at 244.5g a.i./fed, tribenuron-methyl at 4.5g a.i /fed and clodinafop propargyl at 15.75g a.i/fed) mixing with 1% urea increased the herbicides efficiency in controlling the annual weeds by about ( 90.2, 65.9 and 44.5 %).”

Other claims from this paper (19)
- Intervention effect Recommended-rate isoproturon plus diflufenican gave 93.6% control of total annual weeds.
- 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 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.
