General Recommendations for Managing Nematodes in Field Crops (FS-1082)

Nematodes are an economically important pathogen of many crops in Maryland. Significant yield loss can occur if nematodes are not managed properly. This factsheet serves as a broad introduction to nematodes as plant pathogens and serves as a general guide for sampling and managing nematodes in Maryland.

Managing Herbicide Resistant Common Ragweed (FS-474)

Common Ragweed (Ambrosia artemisiifolia) is a native summer annual weed of many cropping systems in the mid-Atlantic. It is often encountered as weed in agronomic crops as well as vegetable, orchards, roadsides, and abandoned fields. Common ragweed can thrive in lower fertility soils and is often more severe in reduced or no-tillage situations. In Maryland, populations of glyphosate resistant common ragweed were first confirmed in 2014. Resistance to ALS herbicides was also confirmed the same year. In most areas of Maryland, common ragweed has two-way resistance to both glyphosate and ALS chemistry. In 2017, pockets of three way resistant common ragweed plants were confirmed in parts of Delaware and the Eastern Shore of Maryland to PPO, ALS and glyphosate. Herbicide resistant common ragweed can be very difficult to control in agronomic crops, particularly soybeans.

Evaluation of the performance of a soy protein seed lubricant in corn and soybeans (FS-1127)

With the arrival of a new seed lubricant product, DUST, the University of Maryland evaluated its performance against two common seed lubricants in both corn and soybeans in 2019. DUST is a soy protein lubricant that is a cleaner alternative to commonly available seed lubricants, such as graphite which can create a mess for users of the product. It is also reported to contribute to early plant vigor. Author: Dr. Nicole Fiorellino; Title: Evaluation of the performance of a soy protein seed lubricant in corn and soybeans (FS-1127)
