Fumigation with Muscodor albus volatiles for the control of postharvest decay
… The biological control, particularly by biofumigation, has been pointed as an alternative to reduce postharvest losses. However, for using in the plant disease control, the previous knowledge regarding etiology is essential. A systematic etiological survey was, therefore, conducted in the …

Sequential cropping of vegetables using plastic mulch, trickle irrigation, and soil fumigation
… trickle irrigation, plastic mulch, and soil fumigation was performed in two separate experiments. In 1980, cabbage (Brassicae olericea L. var capitata cv. Market Prize) was followed by tomato (Lycopersicon esculentum Mill cv. Pik Red). In 1981, cabbage was followed by broccoli (Brassicae …

Soil solarization and soil additives as alternatives to preplant fumigation in annual plasticulture strawberry production
Fumigation before strawberry (<i>Fragaria×ananassa</i> Duchesne) planting was a common practice as they are susceptible to numerous pests. Methyl bromide, the colorless, odorless gas, was the chosen fumigant for growers until it was classified as an ozone-depleting substance and its use was …

Effect of Ethanol Vapor Fumigation on Survival of Salmonella enterica biofilms on Whole Black Peppercorns
Salmonella embedded biofilms were formed on whole black peppercorns and treated with ethanol vapor under atmospheric pressure conditions and under vacuum assisted pressure conditions. The effect of ethanol vapor, heat and vacuum pressure on the survival of multiple Salmonella enterica serovars …

Response of selected warm-season turfgrasses and ornamental monocots to short-term, high concentration, ozone fumigation
Ozone (O3), one of the most powerful oxidants known, is phytotoxic at high levels in the troposphere, or ground-level. Effects of acute ozone exposure for two consecutive days was examined on Bermudagrass (Cynodon dactylon), centipedegrass (Eremochloa ophiuroides), zoysiagrass (Zoysia japonica), …

Effect of O3 fumigation on photosynthesis and growth of quinoa and its interaction with drought and elevated CO2
… to well-watered plants from 14 to 21 days fumigation. The exhibition of a positive ?VL-band from the start in plants treated with 120 ppb O3 indicates a strong concentration-dependent O3-induced inhibition and decrease in parameters like reduction of end electron acceptors per reaction …

Inactivation of Salmonella enterica and Enterococcus faecium on Whole Black Peppercorns and Cumin Seeds Using Steam and Ethylene Oxide Fumigation
… steam treatments and ethylene oxide (EtO) fumigation. The objectives of this research were to identify the effectiveness of a lab-scale steam apparatus and a commercial EtO process on the inactivation of Salmonella enterica or Enterococcus faecium NRRL B-2354 inoculated whole black …

Responses of gas exchange and the antioxidant system of soybean cultivars to ozone and/or sulfur dioxide
… the SO₂ exposure and in the first 2 hr of O₃/SO₂ fumigation. During O₃/SO₂ exposure, the estimated pollutant fluxes were 50% and integrated doses were 25-30% of O₃ or SO₂ when fumigated singly. During O₃ fumigation, cv Dare exhibited a higher O₃ flux and integrated O₃ dose. However, cv Essex …

An Integrated Approach for Controlling Verticillium Wilt of Strawberry
… to alleviate threats to production. Alternative fumigation practices such as crop termination have recently been investigated, and the integration of crop termination with bed fumigation and host resistance can play an integral role in control of Verticillium wilt. A field trial was established …

In vitro studies of the impact of ozone and sulfur dioxide on the pollen of Fraser fir (Abies fraseri (Pursh) Poir.)
The impact of in vitro ozone and sulfur dioxide fumigation on pollen from two Fraser fir populations was examined. Populations were located at Mt. Rogers, Va, and Mt. Mitchell, S.C.. Two age groups "young" (less then 30 years old) and "old" (more then 40 years old) were examined within each …

The Effect of Foliar and Root Pathogens of Soybean on Selected Host Parameters
The use of soil fumigation (using metham) and foliar fungicide sprays (using benomyl) reduced pathogen populations in foliar and soil components. Individually they improved some aspects of soybean health, but when used together these chemical controls resulted in consistent increases in plant …

The reaction of ethylene oxide with some proteins, amino acids and vitamins
A report that the ethylene oxide fumigation of animal diets reduced their nutritive value has prompted a more detailed study of the reactions of this commercially-used fumigant. It has been demonstrated that the 24-hour fumigation of commercial casein, egg albumin and lactalbumin with ethylene …

Comparative physiology of radish populations with differential sensitivity to O₃ and SO₂
… raised and exposed to O₃ or SO₂ with the same fumigation regime used for the parents. The plants were harvested 30 days after emergence and dry weights were determined. Plants selected for O₃ resistance (O3R) weighed significantly more than either plants selected for sensitivity to O₃ (O₃S) or …

The effect of processing method of broiler litter on pasteurization, nitrogen loss and nitrogen utilization by sheep
… of 0.63 and 2.54 cm; and ethylene oxide (ETO) fumigation for 30 min. or longer. Moisture and uric acid nitrogen were lowered (P < .01) for dry heat and the PFA processes. Autoclaving and PFA addition followed by dry heating lowered (P < .01) NPN. Ammonia nitrogen was reduced (P < .01) by all …

Chemical treatment of bread corn during milling process to eliminate insect contamination
… of this contamination. In connection with the fumigation of stored grain, tables were prepared showing the results of fumigations of grain insects with more than 400 chemical compounds. Those compounds which appeared to be best suited for this type of treatment of the corn, were then listed in …

Ozonation Systems as a Non-Chemical Alternative for Stored Grain Protection
… ozonation was 55% more expensive than contract fumigation, but 29 and 43% less expensive than ambient aeration and grain chilling, respectively. Two comparative case studies for eradication of adult insects in stored grain on-farm (i.e., food grade maize and HRW) showed that traditional pest …

Studies of Nematodes Associated With Maize, Soybean, and Sunflower in Illinois and the Republic of Zambia
… in fumigated plots. Control of M. javanica with fumigation increased sunflower yield by 56%. Increased maize yields were associated with fumigation and subsequent control of S. brachyurum. Infection of soybean roots with Neocosmospora vasinfecta var. africana was recorded for the first time in …
