Strategies to screen horticultural crops for graft-transmissible agents, particularly viruses and phytoplasmas, have advanced substantially over the past decade. Tests used for Vitis and Prunus are reviewed in detail, including both biological indexing procedures and laboratory-based assays. Despite advances in laboratory molecular-based detection techniques, a strong case is presented for the ...

Introduction With the implementation of consistent federal standards for products marketed as “organic” in October 2002 (USDA/AMS, 2002), organic production and consumption is expected to increase beyond current organic sales of $10 billion in 2001 (OTA, 2002). In 1999, Iowa farmers reported 150,000 acres of organic production to the Iowa Department of Agriculture and Land Stewardship survey (I...

Objective: Economic analysis was performed for the main horticultural crops in Buin Zahra (pistachio, peach, nectarine, and apple). There were dependent and independent variables in this research. Methods: The independent variables were planting method (mechanized and conventional), land area used for fruit production, and land ownership. The maximum energy used, mostly in the form of fossil fu...

The microbiological safety of horticultural plants (vegetables, fruits, spices, flowers, other edible crops, ornamental plants, etc [...]

Pesticides are essential for agricultural and horticultural crops production. Pesticides are commonly classified as insecticide, fungicide, herbicide, rodenticide, etc. These pesticides act against insects, rodents, weeds which are harmful in agricultural or horticultural planting. Normally, farmers use the pesticides following the instruction written in the package. In most cases, the pesticid...

This article investigates the effects of EM fungicides on horticultural crops, and explores mechanism action application fungicides. Research has shown that can significantly increase growth rate yield improve soil quality, enhance crop resistance also contribute to environmental protection sustainable development. Therefore, in production crops high value promotion prospects.
