Aphid Control on Louisiana Pecans, 1976

Two similar but independent experiments were conducted to control yellow aphids on pecans at Monroe and Shreveport, LA. At Monroe, the experimental design was a randomized block design consisting of 2 blocks with 3 trees per treatment per block. The trees were "Stuart" and "Schley" cultivars. Applications were made on June 28 with a Meyers 2A42 sprayer with each tree receiving ca 33 gal of spray. Evaluation occurred on July 2 by counting the aphids present on 10 randomly selected compound leaves per tree. At Shreveport, the experimental design was a randomized block design consisting of 3 blocks with 2 "Success" trees per treatment per block. Applications were made July 9 with a John Bean 957 sprayer with each tree receiving ca 33 gal of spray. Evaluation occurred on July 13 by counting the aphids present on 10 randomly selected compound leaves per tree. Data were subjected to analysis of variance.
