Abstract
The tests were established in Graham Co. (SouthEastern Arizona), Pinal Co. (Central Arizona) and Pima Co. (SouthCentral Arizona). The tests were similar in nature and consisted of applying 1800 to 2000 kg /ha of granulated sodium chloride with various types of fertilizer spreaders in strips (usually 8 to 16 beds in width), through old cotton soils heavily infested with Phymatotrichum root rot. Alternating non -treated strips constituted check treatments. All plots were replicated at least 4 times. After application the sodium chloride was disked or plowed into the soil and the beds shaped. These field operations were followed by irrigation, bed mulching, and subsequent planting. Varieties in these trials consisted of commonly planted Pima varieties (Gossypium barbadense) and upland varieties (G. hirsutum) both of which are equally susceptible to the disease. Stand counts were made after emergence and disease evaluation determined by use of aerial infra -red photography, visual observations and yield data. The middle 4 rows of each plot was harvested with a 2 bed harvester. No reduction in incidence of Phymatotrichum root rot was seen in any of the sodium chloride tests established during 1977, 1978, and 1979. Also, no carry -over effects have been noted in any of the tests. The results of a typical field test during 1979 at Marana, Arizona is shown in Table 1.
