PPFS-MISC-7: Genetically Engineered Crops: A Review of Concerns and Benefits

Paul Vincelli | Oct. 1, 2016 (New)

Genetically engineered crops are plants that have had their genetic material (DNA) purposefully manipulated in the laboratory to produce a particular beneficial outcome. These types of crops are often called genetically modified organisms, or GMOs. Commercial genetically engineered crops are designed to have limited and precise genetic changes that provide one or more benefits to humans or the environment.

PPFS-MISC-2: Some Principles of Fungicide Resistance

Paul Vincelli | Jan. 1, 2014 (New)

Fungicides are important tools in modern crop production. Unfortunately, one of the risks of using these products is that fungi sometimes develop resistance to them. Resistance development is a concern because the products may become less effective--or even useless--for controlling resistant pathogens and pests. This is a concern for all pesticides, including fungicides, insecticides, and herbicides. This fact sheet is intended to help pesticide applicators better understand this process.

PPFS-MISC-6: Assessing Foliar Diseases of Corn, Soybeans, and Wheat: Principles and Practices

Don Hershman, Paul Vincelli | Nov. 1, 2011 (New)

This publication provides basic information on how to conduct disease assessments in on-farm trials. The focus is on foliar diseases, since root diseases are much more difficult to assess properly. The publication begins with fundamentals of proper design of field trials.

PPFS-MISC-4: Real-time PCR Detection of Xylella fastidiosa is Independent of Sample Storage Time and Temperature

Bernadette Amsden, John Hartman, Paul Vincelli | Nov. 1, 2010 (New)

The xylem-limited bacterium Xylella fastidiosa, first associated with Pierce's disease of grapevines and alfalfa dwarf disease in 1973 (4) continues to be an economically important pathogen of several commercial crops. It also causes bacterial leaf scorch in urban shade trees such as sycamore, oaks, maples, mulberry, and elm (5). The usual course of action, in an effort to control the spread of this pathogen by insect vectors (9), is to prune out infected branches and vines or to rogue infected plants. Therefore, timely testing of suspect hosts is important.
