Dry them, put them in a paper bag, and send them to the laboratory for analysis. Samples should be representative of the whole field, but if plants in a particular area are doing poorly, sample that area separately. A tissue analysis should be done every second year. Many of these studies included herbicides that have yet to receive a label for use on pumpkins, so making any recommendations those herbicides is still premature. A comparison of the 1993-1995 average and the 1996 results are summarized in the table below.
Average yields are pounds per fruit.
In the multiple rate studies of 1996, the highest yields were recorded from the plots that received 0.5 pounds of Command plus 1.00 pound of Curbit. Performance of the Command-Curbit combination was very consistent over the 4 year period. Stewart's Wilt on Sweet Corn Stewart's wilt and leaf blight is a disease that is usually a concern for sweet corn growers in the southern half of Illinois. The disease was not a major problem last season, but in 1995 Stewart's wilt caused significant losses throughout the central part of the state. The seedling wilt phase of the disease results from seedlings being infected in the 3 to 5 leaf stage or sooner.
