Varsol Tried on Black Locust Seedbeds

During the summer of 1950 we had occasion to try Varsol on black locust seedbeds at TVA's Clinton Nursery, It wasn't a planned experiment, but rather a case of necessity. We had a long period of wet weather and couldn't get on four of our beds with cultivators. Rather than lose these beds to crabgrass, we decided to try spraying with Varsol. We used an application rate of 25 gallons per acre on two of the 400-foot beds and 35 gallons per acre on the other two. Each bed was sprayed twice, with an interval of three weeks between sprayings. The first was applied when the black locust seedlings were about four inches high, and still green and succulent. The crab grass was half this high and completely covered the beds. This first spraying killed about half of the grass--and about a third of the seedlings. That's roughly 27,000 of the estimated 80,000 in the four beds.
