蘆筍園除草劑應用區域試驗(第四年)

Abstract

1.供試除草劑 A-2591, Monuron, Simazine, Lasso, Diuron 在蘆筍園均有良好之雜草防治效果，尤其 A-2591 處理對尖葉雜草類及闊葉類雜草之防治最有效。 2.在雜草發生多的蘆筍園施用 A-2591 4kg/ha，不僅有控制雜草發生之效果，而且對蘆筍嫩莖產量可增產20%。但如施用在雜草發生少之園地或季節則對蘆筍嫩莖之產量可能有不利之影響。故 A-2591 之適當用量似乎可減為每公頃 3 kg。 The applications of A-2591 (4kg/ha), Monuron (0.8kg/ha), Simazine (1kg/ha), and Lasso (1ℓ/ha) + Diuron (0.5kg/ha) were evaluated at the main asparagus production areas of Taiwan. The results showed that all herbicides tested gave excellent weed controls, especially the treatment of A-2591 at the rate of 4 kg per hectare gave the most effective control of narrow-leaved and broad-leaved weeds.
