In the near future, growers will have access to several new crop cultivars with resistance to a wider range of herbicides than has been available before. Here is a quick summary of these new crops and when they are expected to reach the market.

The EPA is registering the herbicide Enlist Duo from Dow AgroSciences with first-time-ever restrictions to manage the problem of resistant weeds.

There is plenty of information on fall herbicide treatments in the C.O.R.N. newsletter archive and on other university websites. Our philosophy on this has not changed much over the past decade. A few brief reminders follow:

Currently, Johnsongrass is the only grass listed on the Missouri Department of Agriculture's noxious weeds list.

Now is the time to think about controlling summer annual weeds prior to seed set in cropping situations where this is possible.

As you travel over your field with your herbicide this season, you may be considering adding a fungicide to that pass. If so, there are a few things to think about. In general, early fungicide applications on corn (V5-V7) have not been shown to provide much yield benefit over no treatment (average is +1 bushel per acre). In repeated trials across the country, we see the best opportunity for yield response with a treatment at tassel (average: +8 bushels per acre). However, there are some situations in which an early treatment may be more economical.

Hopefully, most of our full-season soybean crop has been managed for weeds by this time of the summer and some growers have planted or are still considering double-crop. There is still time to ensure your soybean weed control programs worked by scouting those full-season soybeans for escapes and by selecting effective herbicides to control weeds in double-crop soybeans.

This year, there is a very high degree of variability across the state with regards to soybean height, canopy coverage and overall crop condition.

Corn planted in early May under "less than ideal conditions" or pounded by rain is just coming up. There are undoubtedly some questionable stands, but what can be done at this late date?

Herbicides can cause serious injury to plants when applied improperly or when non-target drift occurs. Here are five things to consider to avoid crop injury when applying herbicides this spring.
