The degree of pollution of rivers resulting from human activities is assessed using different biotic indices. The latter reflect the ecological status of a river based on the quantity and diversity of organisms selected as bioindicators, due to their ecological preferences and tolerance to pollution. This is the case of diatoms, algae consisting of a single cell surrounded by a silica skeleton, recommended by researchers as one of the ideal bioindicators for rivers and lakes.

Many US waterways carry a variety of pollutants, but not much is known about the composition or health effects of these chemical combinations. A new in-depth study, however, is providing insight as it shows the mixtures are more complex than expected and contain compounds that could potentially harm aquatic species.

A recent study made headlines with the conclusion that more than one third (35.6 percent) of U.S. households will find their water bills have grown unaffordable over the next five years if rates rise at projected levels. This will nearly triple the number of households that currently cannot afford water services, per the study.

Beef cattle producers are rightfully proud of producing a "good" product but sometimes go to extremes on weight endpoints to achieve this product. We should really be assessing the cost of putting on those extra pounds of fat if we are going to stay in business.

With many producers faced with the possibility of replant corn, some important decisions may need to be made with regards to controlling the failed crop plants along with the usual weed management considerations. Special consideration must be taken when the corn is herbicide resistant, such as Roundup Ready and Liberty Link hybrids. As usual, the timing of applications is also important.

Rose Rust is uncommon on ornamental roses in Pennsylvania but it does occur, especially in mild, wet spring conditions.

The wet and uncooperative weather has resulted in delayed pre-emergence applications for many producers. Reconsideration of delayed pre-emergence and early post emergence herbicide options may be necessary. The weather effects can result in stressed plants with a greater risk to selection and use of certain herbicides.

Herbicide selection in new grass and legume seedings, established hay and pastures, and some guidelines for management based largely on the life cycle of the troublesome weeds in pasture are concerns for some forage producers this season. Some helpful tips for weed management in forages are presented in a simple/straight-forward fashion for your convenience.

Last week I covered four important pest species that can cause trouble this time of year. They were black cutworm, cereal leaf beetle, slugs, and armyworm. This week little has changed and I encourage growers to continue to scout for these pest species to determine if they are infesting your fields and if their populations are economically relevant.

Wheat Scab Monitoring/Modeling efforts have recently estimated the risk to be low. However, if you have wheat flowering now, or set to flower in the next week, consider a spray for scab prevention.
