Abstract : This paper was presented at the 10th conference of the Weed Science Society of Israel, held on 20-21 Dec., 1987 at Rehovot, Israel. In trials, 0.2-0.6 kg fluroxypyr/ha applied pre-em. before or after germination effectively controlled Solanum elaeagnifolium, Convolvulus arvensis, S. nigrum and Datura spp. in cotton without damage to the crop. However, when the herbicide was incorporated before sowing it caused substantial crop damage. At 0.1-0.3 kg pre-em., fluroxypyr was safe to use in Citrullus lanatus cv. Crimson. At 0.08 kg, 60-70 days after germination, fluroxypyr controlled S. elaeagnifolium and Prosopis farcata in C. lanatus cv. Shulamit causing light crop damage but no reduction in yields, whereas at 0.12 kg serious damage and loss occurred. No phytotoxicity was recorded in dates cv. Halaoui, and at 0.25-0.35 kg, fluroxypyr provided good control of P. farcata and C. arvensis though control of Alhagi maurorum was poorer. In mangoes, 0.2-1.2 kg provided effective control of S. elaeagnifolium, C. arvensis and P. farcata and, at the higher rates, controlled A. maurorum without injuring the crop. Good control of S. elaeagnifolium, P. farcata and Kochia sp. (75 cm high) was obtained with over-the-top applications of 0.15 and 0.3 kg fluroxypyr in 2-5 year old Jojoba [Simmondsia chinensis] without permanent crop injury.
