Postplant Weed Survey
Survey weeds after planting but before hand weeding or cultivation to identify germinated weeds and determine the spectrum present. Depending on planting date and location, it is possible that you will find winter annuals, summer annuals, and perennial weeds in various stages.
The most problematic weeds for cucurbits are nutsedge and field bindweed. Common purslane, junglerice, and barnyardgrass are particular problems where climate modification techniques, such as tunnels, row covers, and plastic mulches are used in early spring to promote early harvest.
Recording weed survey results assists in weed management decisions, including herbicide choice, cultivation methods, rotational crops, and other cultural practices. Review records from previous crops to determine which weeds may be in the seed bank and require control. Information collected over a period of years shows population changes and the effectiveness of your management operations.
