Phenamiphos [fenamiphos] and ethoprop [prophos] were effective against Tylenchulus semipenetrans in citrus but DBCP [1,2-dibromo-3-chloropropane] gave the best yield increases. Although numerous nematodes infested mango, fumigation did not increase yields. Litchi trees responded well to fumigation...

During a continuing introduction programme in Israel, the following tree species were found to grow satisfactorily under the conditions of the Jordan Valley, Negev and Arava areas and produce fruits of commercial value: Sclerocarya caffra, Casimiroa edulis, Manilkara zapota, Diospyros digyna [D....

In 1967 trials were begun with terbutryne (Terbutrex 50 WP) for controlling weeds in young orchards (from planting time onwards) in nurseries and in bearing stone fruit orchards. Trials were performed in: (a) fruit nurseries of apple, pear, plum and peach; (b) citrus nurseries of lemon, pommelo and ...

Morphological, physical and biochemical characteristics of sapodilla (cv. Kalipatti) fruits were studied at 15-day intervals between 200 and 275 days after fruit set to assess the optimum stage of maturity. Ripening behaviour, physicochemical parameters and sensory characteristics of the fruits...

Sapodilla fruits (cv. Kalipatti) were dipped in 6% Waxol, Bavistin [carbendazim] (250 or 500 p.p.m.) or hot water (50°C for 10 min.) and packed in 150 gauge thick polyethylene bags with 1% ventilation. Storage decay was high in all fruits except those dipped in 500 p.p.m. Bavistin. Waxol treatment...

Ovules from 10 to 150 days of age and peduncle nodal sections (1 cm) were cultured on MS medium supplemented with glutamine (400 mg/litre), sucrose (3-6%) and agar (0.8%). Growth regulators used were 0-3 mg benzyladenine (BA) and 0-2 mg NAA/litre for ovules and 0.5 mg BA and 2 mg IAA/litre for...

Troyer citrange (Poncirus trifoliata X Citrus sinensis) seedlings were inoculated with G. fasciculatus during transplanting, or not inoculated, and 5-16 weeks later they were exposed either to HCl gas at 110-140 mg/m3 for 20 min or to ozone at 2 mg/m3 for 4 h. HCl caused marginal leaf necrosis, but ...

Avocado and citrus seedlings with or without established Glomus fasciculatus were inoculated with Phytophthora cinnamomi (avocado) and P. parasitica [nicotianae var. parasitica] (citrus), or not inoculated, and growth differences were assessed after 3 months. With avocados, the average height...

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 ...

Studies are reported on spinach, avocado, almond, mandarin, grapefruit and apple.
