Prevention and Control of Palmer Amaranth in Cotton | Palmer amaranth (Amaranthus palmeri), a member of the "pigweed" family, is one of the most troublesome weeds in many southern row crops. Seed can germinate all season and plants can grow to over 6 feet in height. Plants have either male flowers that shed pollen or female flowers that can produce up to 600,000 seed per plant. One Palmer amaranth per 30 foot of row can reduce cotton yield by 6 to 12%. |

Winter Grain Mite | The adult is relatively large compared
to other spider mites and is the only mite of economic
importance with the anal pore (a tan to orange spot
best seen with microscope, but can be seen with a hand
lens) on the upper surface of the abdomen. |

Integrated Pest Management Peanut Scouting Manual | In the competitive global peanut market, you need to lower production costs. At the same time, you also need to keep pesticide residues in peanuts to a minimum; protect rivers, streams, and lakes from runoff; and prevent chemicals from leaching through the soil to groundwater. Using IPM to protect crops only from pests that are likely to cause economic losses is a good way to meet these goals.

Cereal Leaf Beetle, Biology and Management | Cereal leaf beetle, a native to Europe and Asia, was first detected
in Michigan in 1962. Since that time it has spread throughout
most of the mid-western and eastern United States and
has become a significant pest of Virginia and North Carolina
small grains. This insect can become very numerous in small
grain fields and the larvae are capable of reducing grain yield
by eating the green leaf tissue.

The Peanut Southern Corn Rootworm Advisory | The southern corn rootworm (SCR) has long been considered
a major pest of peanuts in North Carolina and Virginia.
However, researchers and Extension faculty at Virginia
Tech and NC State have determined through more than 400
commercial field trials that the majority of peanut fields
do not need to be treated. They have developed and tested
a simple-to-use advisory that identifies those fields not at
risk for pod damage or economic loss. The Southern Corn
Rootworm Advisory can save you time and money as well as
help you use insecticides more efficiently. |

Corn Earworm Biology and Management in Soybeans | Corn earworm, Helicoverpa zea, is the most common and destructive insect pest of soybeans grown in Virginia. Although infestation severity varies, about one-third of our acreage is treated annually. This costs farmers 1.5 to 2 million dollars annually, and requires the application of many pounds of insecticide to crop lands. We may never eliminate this pest from Virginia soybeans, but knowledge of the biology and use of best management practices can help limit insecticide controls to those fields that meet economic threshold criteria. This publication provides current information on corn earworm biology, prediction of outbreaks, pest advisories, scouting procedures, and recently revised economic thresholds. |

Soybean Reproductive Development Stages | Remove the soybean plant at ground level to make it easier to stage. Examine each main stem node one at a time to determine the development stage. Focus on the top four nodes that contain fully developed leaves (shown below). A fully developed leaf is one that is located immediately below a node containing a leaf with unrolled or unfolded leaflets (leaflet edges are no longer touching). The soybean crop is considered to be at a particular stage when 50% of the plants reach that stage. Listed with stage description for R1 through R6 are the approximate number of days to R7, or physiological maturity, for full season (FS) soybean planted in May and double crop (DC) soybean planted in June/July. |

Soybean Insect Guide | Numerous kinds of insects can be found in soybeans. Most are beneficial
or harmless, but some can cause yield loss and even crop failure if not
controlled. |
