Weed control in onions can be challenging. Onions have various challenges that make weed control difficult. They grow slowly early in the crop cycle and never achieve a good competitive crop canopy to suppress weeds. Also, given the high density plantings, it is not possible to effectively cultivate the beds. In addition, given the close spacing between plants, it is difficult to hoe out weeds without risking damage to the onion stand. In conventional onion production there are a number of materials that can provide excellent weed control (see Figure 1). The timing of application of the materials can be tricky because some weeds may grow quickly and be difficult to control by the time the onions reach the 2nd...

One of the biggest challenges to growing a vegetable garden in a non-raisedbed situation can be the weeds. The can make the garden unsightly, compete with the vegetable plants you really want and make you feel overwhelmed in trying to manage them. Here is your five step plan to a better garden with fewer weeds:
Step one: Control existing weeds. If your garden has any weeds, you first need to take care of them prior to doing anything (except planning). You have a couple of options. You may rototill your garden to dig under existing weeds or you can spray out the garden with a non-selective herbicide such as glyphosate (Round-up). ...

Good things come to those that wait. Well, when it came to getting a registration for prometryn for use on cilantro, wait we did. I recall doing the first trials on prometryn for use on cilantro in 1999. Since that time we worked closely with Becky Sisco at the Western Region of the IR4 Program to establish the tolerance for this material on cilantro. IR4 did their part and the packet was submitted to EPA. Given that cilantro is a very minor crop, the label was ultimately grouped with carrots, parsley and okra in order to attract more attention for the label request, and so that it would not get lost amongst the many other label requests that EPA deals with. The packet was ultimately processed and sent back to Syngenta, and in...

The development of improved cultivation technology for row crop production has been an active area of research, and has made significant progress in recent years. Currently, standard cultivation removes weeds from the majority of the bed using sweeps, knives, coulters and blades. Typically a 4-inch wide band is left around the seedline. Weeds in the uncultivated band are typically removed by hand, and the density of weeds that occur there, determines how laborious and costly subsequent hand weeding will be.
There is technology to remove weeds from the seedline and it generally falls into two categories: 1) blind cultivation and 2) computer assisted cultivators. Implements used for blind cultivation are not guided by a...
