Abstract Experiments were conducted in Ash-Shoubak area of Jordan from June 2003 to September 2005 to study the effect of three apple rootstocks on the development of the small red-belted clearwing borer, Synanthedon myopaeformis (Borkh.) (Lepidoptera: Sesiidae), under field conditions. Mondial Gala apple trees grafted on the dwarfing rootstock M9 and the semi-dwarfing rootstock M26 were equall...

AM-toxins are host-specific phytotoxins of the Alternaria alternata apple pathotype, which induce necrosis on apple leaves. In this study, we developed a new assay to measure the necrotic activity of AM-toxin analogs using cultured leaves from meristem cells. This method was not only more sensitive to AM-toxin I, but also more reliable than the previous one that used tree leaves due to the homo...

Mass releases of two parasitoid species, Aphidius matricariae and Ephedrus cerasicola, may provide an alternative measure to pesticides control the rosy apple aphid Dysaphis plantaginea in organic orchards. As exploratory study, we tested if presence flower strips between tree rows could improve action three early releases––and other naturally present enemies––on colonies number aphids per tree...

The objective of this study was to evaluate the influence of organic (cattle manure) and inorganic fertilizers [composite NPK (15:15:15)] and natural zeolites on soil properties, vegetative growth and yield of apple plants grown on vertisol under Cacak conditions (Western Serbia). The results showed that the combined fertilization induced a decrease in acidity, an increase in humus content, a p...

In highly solar irradiated areas, apple production can face challenges due to high evaporative water demands. Shading be used lower irrigation requirements and make growing more sustainable. this trial, a white exclusion net (40% shading) integrated with rain protection was compared regular anti-hail black (20% shading), on Rosy Glow apple. Crop physiology, yield quality parameters were monitor...

Boron deficiency was first recorded in Australia in the 1930s in apple trees growing in Tasmania and New South Wales. Subsequently the deficiency was found in a wide range of pasture and crop plants. Crops with higher boron requirements such as lucerne, sunflowers, rapeseed, cauliflower and apples are most likely to respond to boron. Pine trees, which are commonly used in tree lots and as windb...

Autonomous operation and information processing in an orchard environment requires an accurate inventory of the trees. Individual trees must be identified and catalogued in order to represent their distinct measures such as yield count, crop health and canopy volume. Hand labelling individual trees is a labour-intensive and time-consuming process. This paper presents a trunk localisation pipeli...
