| ABSTRACT: Using an adjuvant to optimize and increase the foliar activity of post emergence herbicides is an acceptable way to reduce their side effects. Field researches were conducted to detect a suitable adjuvant for two post-herbicides namely, isoproturon+tribenuron and pyroxsulam against little seed canary grass (Phalaris minor) and field bindweed (Convolvulus arvensis). Treatments were, isoproturon+tribenuron at 1,025 g a.i. ha-1 (recommended dose) and pyroxsulam at 140.6 g a.i. ha-1 (recommended dose) alone or their reduced dose (75% of the recommended dose) isoproturon+tribenuron at 769 and pyroxsulam at 105.5 g a.i. ha-1, tank mixed with three different adjuvants viz. alkylethersulphate sodium salt at 400, fatty alcohol ethoxylate at 200 and... |
