On January 12, 2016 the Federal EPA label for Kerb SC was reinstated for leaf lettuce. The registration on leaf lettuce was pulled in 2009 and Dow AgroSciences has been working to reregister Kerb since that time. As part of this reregistration effort, Kerb was reclassified as “not likely to be carcinogenic to humans” which freed up space in the risk cup. Of particular interest are the preharvest intervals allowed in the label:

The current automated weeding machines use cameras to detect plants, and a computer algorithm to process the image, calculate which plants to keep/remove, and activate a kill mechanism. These machines are capable of cultivating within the seedline and removing weeds that would otherwise be left by traditional cultivation. The machines used in these studies included the Robovator, F Poulsen Engineering Aps, Hvalsø, Denmark and Steketee IC Weeder, the Netherlands. Both of these machines use a split knife that as it...

The Apiaceae or carrot family includes important vegetable crops such as carrots, celery, cilantro, dill, fennel and parsley. All of these crops have a distinctive inflorescence known as an umbel. They also produce aromatic oils that give these plants their characteristic aromas and flavors. Many of these crops germinate slowly and are quite susceptible to weed pressure early in the production cycle. As a result, crops like celery are nearly 100% transplanted to give the crop a head start in the.../span>
Weed control in cool-season vegetables can be quite challenging. However, there are a number of practices that provide growers with certain advantages:
- Short-season crops such as lettuce and spinach that allow for rapid turnover of the crops (e.g. 30 to 65 days), frequent cultivation (lettuce) and/or complete hand removal of weeds prior to mechanical harvest (clipped spinach and baby lettuce)
- High value of the crops allows for the use of intensive hand-removal of weeds, often prior to seed set
- Small production blocks that allow for careful observation and intensive management
All of these strategies have basically made some of the most troublesome weeds such as field bindweed and yellow...
