Weed Control in Garlic (Allium Sativum L.)

Abstract

to evaluate the efficiency of some chemical weed control treatments as pendimethalin(Stomp extra45.5%CSatrate at rate of 1.7 Liter/fed.),butralin(Amex 48% EC at rate of 2.5 Liter/fed.) and fluroxypyr (Starane 20% EC at rate of 200 cm 3 /fed.) alone or with hand hoeing once or twice on weed, balady garlic yield and yield components and residues limits for herbicides. The obtained results revealed that hand hoeing treatment at three times gave highest fresh and cured yield followed by treatments with Stomp extra 1.7 L. /fed.+ two hand hoeing and Starane 200 cm 3 /fed.+ two hand hoeing. While the lowest values of fresh and cured yield were obtained from control (without) followed by Starane, Amex and Stomp extra alone. These results may be due to the better effect of hoeing on removing weeds than herbicides and poor effect of herbicides in killing the weeds specially when used alone. There are residual effects for using herbicides but there were below detection limit 0.01 ppm for butralin 48% at 2.5 L/ fed. & pendimethalin 45.5% at 1.7 L/fed. and 1.0 ppm for fluroxypyr 200 cm 3 /fed. in cloves.

A modalidade de aplicação afeta a seletividade de herbicidas para a cultura do alho

“…According to Guerra et al (2020) and Hassanein et al (2012), this herbicide is a great alternative for weed control in garlic crops. In addition, it presents long residual period (Mallik et al, 2017).…”
