Flame “cultivation” for weed control was developed about 50 years ago. The practice was very popular with Southern cotton farmers through the 1950s and 1960s, but lost favor when petroleum prices rose drastically in the 1970s. There is now a new interest in the practice of flame cultivation as a partial or total replacement for herbicides in vegetable crops. This interest is fueled by three factors: 1) an increasingly negative public perception of herbicides on vegetables, 2) a very limited selection of herbicides labeled for vegetables, and 3) limited efficacy of some of the herbicides that are registered. Flame cultivation, in combination with mechanical cultivation, can replace or supplement herbicides in some vegetable crops. The mode of action of flame cultivation is the bursting of cell walls in the weeds as the weeds are heated by a carefully directed LP gas flame. With most vegetable crops, the crop plants must be protected in some manner. This can be done with a water shield (flat fan water spray), height differential between weeds and crop, physical shield, etc. Much of the early work on flame cultivation of vegetables was done with sweet corn. Work is now underway on flame cultivation of lima beans and southernpeas, where multiple flame cultivations have proven effective at controlling weeds for which no herbicide is available.

Field studies to determine the effect of flame cultivation on cotton pests and beneficial insects were conducted in 1994. Mortality of caged tarnished plant bugs and convergent lady beetles located at the soil surface and canopy heights of 10 and 20 cm above the ground in 25- to 30-cm cotton was recorded after flaming at two liquid propane-gas (LP-gas) pressure settings with or without water-shield protection. Air temperatures, measured proximal to insects during flame treatments, were lower at higher levels in the cotton canopy regardless of LP-gas pressure and the presence or absence of water-shield protection. A mortality of 100% was observed at the soil surface for both insect species in all treatments. Plant bug and lady beetle mortality was lower at the 10- and 20-cm heights relative to soil surface values after flaming at 100 kPa LP-gas pressure. After treatments at 175 kPa, only the mortality of lady beetles at 20 cm above the ground was lower than mortality obtained at the soil surface and 10-cm height. Although flaming induced lady beetle mortality, these beneficial insects were not affected to the same extent as plant bugs at higher canopy levels.

AbstractNatural nuclear reactors provide unique evidence in helping to understand the processes that might occur over long timescales in radioactive waste disposal sites. In the presented work, the extent and kinetics of oxidation of core material from the Oklo-Bangombé natural reactors are investigated. The X-ray powder diffraction analysis shows that the uraninites core samples from the Bangombé Reactor and Oklo Reactor 2. and Oklo Reactor 13 have the same unit-cell parameters as synthetic UO2.25. A significant amount of fourmarierite, Pb(UO2)4O3(OH)4 4H2O, was identified in the core samples from two shallow reactors Bangombé and Oklo 2, but not in the deeper reactor Oklo 13. The results of U(IV)/U(IV) measurements indicate that the extent of oxidative weathering of shallow reactors (Bangombé and Oklo 2) is greater than for the deeper reactor Oklo 13. Evaporable organic compounds found in the uraninite inclusion containing “bitumen” at the edge of Okelobondo Reactor (400 °C) and in the black shale immediately above the Bangombé Reactor (260 °C) may work as a reducing buffer or/and a hydrophobic water shield to depress the oxidative dissolution of the uraninite cores.
