Essential oils from four plants, i.e. geranium, rosa, lemon and mint were tested for their activity in vitro and in vivo against Rhizoctonia solani and Fusarium oxysporum f. sp. phaseoli, the cause of root rot and wilt of beans. In vitro, they were found to have an inhibitory effect against the mycelial growth of R. solani and F. oxysporum f. sp. phaseoli. Complete inhibition in fungal growth w...

The most serious disease problem in fraser fir (Abies fraseri) Christmas tree production is phytophthora root rot (PRR). The efficacies of six fungicide treatments in preventing PRR incited by Phytophthora cactorum and P. drechsleri in 2-year-old fraser fir seedlings were evaluated in 2010 and 2011 in central Pennsylvania. The study examined five fungicide drench treatments [dimethomorph, foset...

Sodium alginate, irradiated by Co-60 gamma rays in solid state, elicits plant growth promoting responses in various plants. Irradiated sodium alginate (ISA) was applied as a foliar spray on mint (Mentha arvensis L.) to investigate its effect on plant growth, physiological attributes and herbage yield as well as on content and yield of essential oil and its components (menthol, L-menthone, isome...

Seeds of chickpea inoculated with Rhizobiumwere sown in pots supplemented with different doses of cadmium (0, 25, 50 or 100mg per kg of soil). At the stage of 30 days after sowing (DAS), the plants were sprayed with 20 mM solution of proline and were sampled at 90 DAS to assess the various parameters. The foliar treatment of proline resulted in the alleviation of the adverse effects generated b...

The "Carota di Polignano" (Polignano Carrot - PC, Daucus carota L.) is a multi-colored landrace, cultivated in the Southern Italy, whose colors range from yellow to purple. Iodine is an essential micronutrient for humans, since it is a key component of thyroid hormones, which regulate the growth and development of the human body. The main source for iodine assumption is represented by diet, but...

The herbicidal activity of Withania somnifera (L.) Dunal against the noxious weed parthenium (Parthenium hysterophorus L.) was evaluated. In a laboratory bioassay, the effect of aqueous, methanol and n-hexane shoot and root extracts of 5%, 10%, 15% and 20% w/v concentrations (on a fresh weight basis) of W. somnifera were tested against the germination and seedling growth of parthenium. In gener...

We investigated the effects of coloring agent and potassium sulfate (K2SO4) foliar sprays, reflective aluminium porous film covering on orchard floor enhancement red peel coloration in ‘Hongro’ apples. Foliar spray sulfate, mulching before harvest increased Hunter a value anthocyanin content fruit peels at harvest. In addition, micro-porous had best effect promoting fruits lower inner canopy, n...

Insecticides, fungicides, and foliar fertilizers are all used in the production of watermelon (Citrullus vulgaris L.) in Florida. In certain areas of the state, particularly in south Florida, pesticides are commonly applied at 5-7 day in tervals to maintain disease and insect control. Growers with large acreages combine insecticides and fungicides so that both can be applied at the required sho...

Field experiment was conducted on cowpea during Kharif 2021 at (CRF) Crop Research Farm, Department of Agronomy, Naini Agricultural Institute. SHUATS, Prayagraj (U.P) India. The entitled as “Response biofertilizer and foliar spray organic amendments economics yield attributes (Vigna unguiculata L.)”, to study treatments consisting three kinds biofertilizers viz.Rhizobium, PSB Rhizobium + types ...

Information on better utilizing airblast sprayers to achieve high pesticide spray application efficiency in nursery tree production is needed. Foliar spray deposition and coverage at different heights inside crabapple tree canopies were investigated for a conventional airblast sprayer operating at four different application rates ranging from 230 to 900 L/ha [24 to 94 gallons per acre (GPA)]. D...
