Recently, EPA approved a master Section 3 label (as of 03/24/2008) for ProlineÔ Fungicide from Bayer Crop Science for use in soybean against soybean rust (Phakopsora pachyrhizi) and powdery mildew (Microsphaera diffusa). To legally use ProlineÔon soybean, growers will need to have in their possession the existing container label as well as the supplemental label that Bayer Crop Science is allowed to market.

The 2007-2008 winter, and the early portions of the spring season, has brought substantial moisture into many parts of the state. With further rain forecasted throughout the state over the next few days and weeks, it is important to understand how early season soybean development may be compromised by several plant pathogenic fungi that cause seed rot, seedling mortality, and root and stem decay.

Considering the cost of nitrogen, we can ill afford to allow weeds to use this expensive input. We conducted an experiment for the past 2 years that provided results that truly surprised us in regard to weeds and nitrogen. Basically, we confirmed that weeds are highly effective consumers of nitrogen.

These tables have been very popular with pest management plan writers because they are simple to follow and the data in these tables are consistent with the NRCS WIN-PST computer program. Four separate references tables are available for the following crops: field crops/potato/commercial vegetables; apples; cherries; and cranberries.

A question was recently asked about restrictions of applying herbicides using nitrogen fertilizer as the carrier. Obviously, a simultaneous application can save the time and expense of separate applications. However, it would be a poor choice if there is a risk of causing crop injury, especially considering the value of the current wheat crop. Summary comments on this issue are provided in this article.
