| Abstract/Contents: | Past studies at the Turf Research Farm of the University of Rhode Island have shown that activated charcoal can absorb various chemical residues and alter their effect on plant growth. Improved grass stands were obtained by using charcoal in chemically contaminated seedbeds. Where sod was transplanted charcoal improved rooting and reduced grass injury. Charcoal also alleviated damage to turfgrass where chemical spills, misuse or overapplication took place. However, the use of charcoal might affect the future performance of pesticides. Charcoal could absorb them thereby reducing their effectiveness. Earlier studies have shown some reduction in the activity of preemergent crabgrass herbicides. Six tests were conducted during 1978 and 1979 to study the influence of charcoal on the subsequent performance of certain fungicides, herbicides and insecticides. The results of these trials are presented in Tables 1 through 6. Charcoal applied 13 days before the use of such fungicides as anilazine (Dyrene), benomyl (Tersan 1991), chlorothalonil (Daconil 2787), cycloheximide (Acti-dione/Thiram), iprodione (Chipco 26019) and triadimefon (Bayleton) did not reduce their effectiveness for controlling brown patch disease and/or dollar spot disease (Tables 1 and 2). Three insecticides used for the control of Japanese beetle grubs were not influenced by charcoal treatment six days earlier (Table 3). The insecticides used were carbaryl (Sevin), diazinon (Diazinon), and trichlorfon (Proxol). The herbicide activity of preemergence crabgrass herbicides such as benefin (Balan), bensulide (Betasan), DCPA (Dacthal) and siduron (Tupersan), was not reduced in soil treated with surface applications of charcoal seven months earlier (Table 4). These four herbicides along with oxadiazon (Ronstar) and prosulfalin (Sward) were not influenced by charcoal applied to the surface of established turfgrass nine months earlier (Table 5). In earlier work we did note some reduction in herbicide activity where charcoal was applied to turf surfaces five months earlier. Herbicides such as 2,4-D, dicamba (Banvel) and mecoprop (MCPP), used for the control of broadleaved weeds such as dandelion, chickweed and clover, performed well when applied 17 days following charcoal use (Table 6). One might expect other postemergence herbicides such as the methanearsonates and bentazon (Basagran) to perform as well. It appears from these studies that pesticides will not be influenced by the earlier use of activated charcoal. With the passage of time absorptive sites on charcoal will become saturated and pesticides can be expected to perform satisfactorily. Pesticides that perform their function on plant foliage are the least likely to be affected. Rains will wash charcoal off of plant surfaces and new plant tissue will be charcoal free. Where charcoal is needed to safely establish turf or prevent grass damage than the concern over a possible disease, insect or weed problem in the future should be of secondary importance. |
