The phytotoxicity of petroleum oil sprays to Vakncia orange (Citrus sinensis (L.) Osbeck) on Poncirus trifoliata (L.) Raf. rootstocks was investigated at Kulnura and at Griffith, New South Wales. Four narrow-range petroleum oils, designated as 206, 212, 214 and 238 oils, were applied as high volume sprays in 3 consecutive years. Annual sprays were applied during the spring, summer and autumn months of November, February and April. Some treatments were sprayed once each year, others twice. The single spray per year treatments involved concentrations of 1.2 or 2% of each oil in February or 2% of

The application of the spray drying technique in the food industry for the production of a broad range of ingredients has become highly desirable compared to other drying techniques. Recently, the spray drying technique has been applied extensively for the production of functional foods, pharmaceuticals and nutraceuticals. Encapsulation using spray drying is highly preferred due to economic advantages compared to other encapsulation methods. Encapsulation of oils using the spray drying technique is carried out in order to enhance the handling properties of the products and to improve oxidation

Abstract Evaluations were made of Scalecide foliar spray oil for control of elm leaf beetle eggs and larvae. Larval evaluations were made by counting larvae on 5 branch terminals/treatment on 24 Jun. Foliar applications were made immediately following the count by spraying until run-off. Very hot, dry conditions existed at the time of treatment. At 4 DAT, the marked terminals were counted again. Mortality was corrected by using Abbott’s formula. Evaluations of spray oils against egg stages were done in a similar manner. Twelve recently laid egg masses for each treatment were marked and sprays

Lack of product identification through the label makes it difficult for the field user to know what product was actually used in experimental studies. A minimum standard for product identification is suggested. Phytotoxicity, while relatively uncommon, continues to cause fears on the part of nurserymen and spray contractors. Factors that must be taken into account before spraying oil include dosage, timing with regard to plant phenological development and climatic conditions, and an awareness of sensitive plant species.

Essential oils (EOs) are known as any aromatic oily organic substances which are naturally synthesized in plants. Exhibiting a broad range of biological activities, EOs have played a key role in numerous industries for ages, including pharmaceutical, textile, and food. However, the volatility and high sensitivity to environmental influences pose challenges to the application of EOs on industrial scale.

Results showed that oxidative stability and initial POV of oils, packing and storage temperature all affected markedly oxidative stability of microencapsulated oils.

ABSTRACT Recent research has led to a next-generation dispersant that potentially provides significant improvements for all spill scenarios where dispersants are an option in addition to extending dispersant use to oils previously considered too viscous. The new dispersant is formulated as a positively buoyant viscous gel with the consistency of honey. This allows delivery as a spray of large (up to 0.5 cm) droplets that are persistent in breaking-wave conditions and adhere to an oil slick rather than being washed off as do many commercial dispersants. The new formulation is roughly 90% active

However special “charge injection” techniques have been used in this investigation to produce combustible sprays of oils.

Bimodal size distributions are found with a central core of larger drops or ligament formations near the nozzle surrounded by a sheath of smaller drops.

Plots were single branches and plot design was a randomized complete block with 5 replications. Applications of oil were made using a hand-operated mister applied to individual branches to run-off. Applications against the first generation of the pine needle scale were made 25 May, shortly after settled scales were noted on older needles. Evaluations of mortality were made by examining 10 older needles 1 inch and 3 inches back from the n

Leaf disk and whole leaf bioassays were conducted to evaluate the repellency and repulsiveness of selected fungicides, insecticides, spray adjuvants, and petroleum-derived spray oils (PDSO) to the two-spotted spider mite, Tetranychus Urticae Koch (Acari: Tetranychidae). Compounds were evaluated for their ability to stimulate the movement of T. urticae from treated to nontreated grape tissue (repellency) and to inhibit their movement from untreated to treated tissue (repulsiveness). All insecticides other than Bacillus thuringiensis and some fungicides were highly repellent. Several insecticide

Spray table tests with cotton Gossypium hirsutum L. leaves demonstrated that petroleum oil/diluent residues caused higher mortality in laboratory susceptible tobacco budworm, Heliothis virescens L., larvae than in a laboratory resistant strain. Paraffinic diluents with bifenthrin caused higher mortality of the susceptible and resistant larvae under conditions of long-term exposure to spray residues than bifenthrin in an isoparaffinic oil or an aromatic solvent. None of the bifenthrin-oil treatments increased mortality above water-bifenthrin in either resistant or susceptible strains.

Bio-oils produced by biomass pyrolysis are substantially different from those produced by petroleum-based fuels and biodiesel. However, they could serve as valuable alternatives to fossil fuels to achieve carbon neutral future. The literature review indicates that the current use of bio-oils in gas turbines and compression-ignition (diesel) engines is limited due to problems associated with atomisation and combustion. The review also identifies the progress made in pyrolysis bio-oil spray combustion via standardisation of fuel properties, optimising atomisation and combustion, and understandin

AbstractExperiments were conducted to evaluate the impact of spray volume, nozzle type, adjuvants, the presence of dew, and their interactions on foliar retention of creeping bentgrass. Tartrazine, a common food dye, was used as a tracer in this study. Increasing spray volume from 95 L ha−1 to 1,500 L ha−1 decreased foliar retention efficiency from 98% to approximately 85%. Compared with flat-fan nozzles, air-induction nozzles delivered similar retention efficiency at all spray volumes evaluated. However, flat-fan nozzles provided higher uniformity and more thorough coverage. Adding nonionic s

Brassicaceous leafy greens are an important crop for small growers but are difficult to produce due to damage by flea beetles. Flea beetles are problematic for growers as they chew many small holes through leaves rendering produce unmarketable. We tested the efficacy of several essential oils, the woven-mesh row cover ProtekNet, and the spunbonded row cover Agribon, compared to organic and conventional insecticides and no spray controls in the spring and fall of 2019. We found that the two row cover treatments (Agribon and ProtekNet) provided the best control of flea beetles and associated dam

Water and paraffinic oils were used to determine variables that affect positive displacement pumps used to meter liquid flow in an air-assist spray system. Components needed to construct an air-assist spray system were described for use in spray chambers and on a tractor for field application of herbicides in ultralow volume (ULV). The flow rate of the pump varied less than 2% for the water and oil as the pump setting was varied from 0 to 100% of the pump's capacity. Linear relationships were shown for both liquids as the voltage input varied from 4 to 13 volts. Air pressures to 100 kPa and li

Powdery mildew of sweet cherry is the most serious disease in irrigated orchards and nurseries of Washington. The fungus infects foliage and fruit, but fruit infections are of primary concern due to the potential for rejection of entire crops. Development of resistance to demethylation inhibiting (DMI) fungicides in the mid-1990s increased the difficulty in controlling this disease. Orchard mildew management programs that utilize oils, DMI and strobilurin fungicides have been developed for use in eastern Washington.

Overall, gs of various-aged leaves was decreased by a large leaf-to-air vapor pressure difference (VPD). In the first experiment, oils with midpoint distillation temperatures (50% DT) of 224, 235, and 247C were applied with a hand atomizer at concentrations of 0, 1%, and 4% oil emulsions in water and 100% oil, all with 0.82% surfactant (by volume).
