Abstract
Sodium azide (NaN3) applied at 134.4 kg/ha as a soil fumigant did not drastically alter the quality of vegetable root crops grown on treated soil. Azide soil treatment had no influence on quality of beets (Beta vulgaris L.) or potatoes (Solanum tuberosum L.). Differences were noted in quality of turnips (Brassica rapa L.) during 1976; however, no differences were found during the 1977 growing season at 2 locations. Azide soil treatments resulted in differences in quality of carrots (Daucus carota L.). Some differences that occurred were beneficial such as increased size and carotenoid content of carrots.
Abstract
In field tests, the most effective film mulch in deterring insects and reducing insect damage to fruits was aluminum. The insects affected were aphids, brown stink bugs, aphid parasites, and Diabrotica spp. Mosaic virus diseases were reduced among aluminum-mulched squash (Cucurbita pepo L.) and cucumber (Cucumis sativus L.) plants. Plant growth, flowering, and fruiting were delayed in tomatoes (Lycopersicon esculentum Mill.) and southernpeas (Vigna unguiculata (L.) Walp.).
