A 4-yr research and implementation project in Michigan apple production showed that deploying pheromone-mediated mating disruption for codling moth, Cydia pomonella L., in an areawide (AW-CMMD) program where mating disruption is established on all apple-producing acreage on individual and adjacent farms, significantly improves control of codling moth. The areawide project was compared with mati...
Understanding effects of land-use changes driven by the implementation of the "Grain for Green" project and the corresponding changes in soil organic carbon (SOC) storage is important in evaluating the environmental benefits of this ecological restoration project. The goals of this study were to quantify the current soil organic carbon density (SOCD) in different land-use types [cultivated land...
In 1996 and 1997 pistachio orchards in Isfahan Province were surveyed to determine the presence and damage levels by Eurytoma plotnikovi Nikolskaya and Megastigmus pistacia Walker. In order to investigate seasonal population fluctuation of E. plotnikovi, larval, pupal and adult stages were monitored in three orchards. In each orchard, 200 nuts with more than 50% infestation to overwintering lar...
there are many problems in yield, quality and and persistence regular bearing in olive trees, one of these problems is nutritional imbalances. this study carried out in order to evaluate nutritional status of olive orchards in tarom region of zanjan province. samples of soil and leaf were taken from 79 olive orchards in june 2012 and 2013 and were analyzed by using appropriate laboratory method...
In recent years there has been a growing interest in the application of geographic information systems (GIS) for the development of spatial decision support systems (SDSS). The current paper presents the development of a GISbased SDSS for precision management of tree crops. The SDSS is being developed within the framework of the '3D-Mosaic' project which aims at optimizing water consumption in ...
Rational application of pesticides by properly adjusting the amount of product to the actual needs and specific conditions for application is a key factor for sustainable plant protection. However, current plant protection product (PPP) labels registered for citrus in EU are usually expressed as concentration (%; rate/hl) and/or as the maximum dose of product per unit of ground surface, without...
Streptomycin is used as a first-line defense and tetracycline as a second-line defense, in the fight against fire blight disease in apple and pear orchards. We have performed the first study to quantitatively analyze the influence of streptomycin use in agriculture on the abundance of streptomycin and tetracycline resistance genes in apple orchards. Flowers, leaves, and soil were collected from...
Aphids are sap-sucking insects that mainly attack shoots and young leaves of peach trees and many other plant species; however, knowledge of the Brazilian aphid fauna is scant. The objective of this study was to identify aphid species collected in peach orchards (Prunus persica Batsch) and to determine their faunal indices for occurrence and dominance. The experiment was conducted from July 200...
