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...

The security of farmland property rights is an important factor that affects investment and succession, farm succession highly significant for achieving sustainable agricultural development. In this study, based on survey data obtained from 1012 apple growers in Shandong Shaanxi Provinces, we analyzed the impact land tenure willingness farmers related paths by constructing binary logistic regre...

The red bud borer Resseliella oculiperda (Rübs.) is a pest insect of apple trees when rootstocks are grafted with scion buds by 'shield budding'. The female midges are attracted to the wounds of the grafted buds where they lay their eggs. The larvae feed on the cambium and destroy the buds completely or partially, leading to bad union of the buds with the rootstocks. Budding strips are used ver...

The purpose of this study is to empirically analyze whether the wholesale price of apples sold in the Korean action-based wholesale market is statistically significantly different at the aggregate and disaggregate levels, or not. It means that the researchers in this study empirically analyzed to identify day-of-the-week effects in Korean wholesale price of apples. The results of this study sho...

Among deciduous fruit crops, maximum sustained yields under ideal conditions reportedly range from 22 MT/ha in sweet cherry to 112 MT/ha in apple: about a 5-fold difference. Root length densities under fruit trees, however, range from about 0.2 km/m in apple to about 12 km/m in kiwifruit: a 60-fold difference. What causes these differences among the root systems of different fruit crops? Patter...

Integrated Protection (IP) in agriculture consists of a set of practices aimed at favoring the set up of a development model characterized by a reduced environmental impact. The application of IP practices in plant disease management by growers and agronomists requires both specialistic skills, historical data and information on chemicals and on low impact techniques for pest management. These ...

Apple growers face new challenges to produce organic apples and now many cover orchards with high-density polyethylene (HDPE) nets to exclude insects, rather than spraying insecticides. However, rainwater- associated wetness favours the development of apple scabs, Venturia inaequalis, whose lesions accumulate on the leaves and fruit causing unsightly spots. Treating the nets with a superhydroph...

Foliar diseases like apple scab result in significant economic losses to growers each year. Assessment in past studies involved only macroscopic disease ratings. More complete knowledge of the fate and behavior of fungicide has been needed to reduce pesticide use with less off-target contamination. Field studies were conducted in a production nursery for over 4 years. A moderately susceptible c...

Plant irrigation water needs are important things to be met so that the plant growth is optimal starting from vegetative phase generative phase. The current hot issue among potted fruit growers problem of dropping ovary (pistil) on plant. Many factors cause fall fruit, one which lack water. This certainly special attention considering nature apple itself, in this study, especially green honey a...
