  • The Latest in Whitefly Control

    Next month’s Greenhouse Canada Grower Day is welcoming leading researchers and crop specialists to help you tackle one of the industry’s biggest challenges. Whitefly is proving to be one of the most difficult pests to control, mainly due to the lack of effective registered chemicals that can eradicate silverleaf whitefly. It is also due to the unwillingness of biological suppliers to ...

  • Using Compost To Control Plant Diseases

    Losses due to soilborne diseases on some greenhouse, nursery and vegetable crops can amount to thousands of dollars per acre annually. Until the 1930s, organic amendments — consisting of animal and green manures, coupled with crop rotation — were principal methods of control. But these approaches were largely abandoned for reasons of cost and inconvenience after commercial fertilizers and the ...

  • LG Sound, controlling algae in irrigation reservoirs

    Algae growth in irrigation water can cause a serious problem. Algae in irrigation tanks can clog the entire irrigation system, such as the pumps, filters, drip-installation and sprinkler nozzles. Besides that the algae and their by-products can also be spread over the irrigated area. In addition, some types of fungi, also present in these waters, can be harmful for the plants grown. Typical ...

  • Combined particle swarm optimization and fuzzy inference system model for estimation of current-induced scour beneath marine pipelines

    In this paper the capability of Particle Swarm Optimization (PSO) is employed to deal with an Adaptive Network based Fuzzy Inference System (ANFIS) model's inherent shortcomings to extract optimum fuzzy if–then rules in noisy areas arising from the application of nondimensional variables to estimate scour depth. In the model, a PSO algorithm is employed to optimize the clustering parameters ...

  • Early growth of flint maize landraces under cool conditions

    Cold stress is a major factor that limits the success of environmentally sound cultivation of maize in central and northern Europe. This study evaluated the early growth of seven groups of Swiss Flint maize landraces (Zea mays L. ssp. mays) of different geographic origin under controlled cool conditions by assessing shoot and root traits. Measurements of plants, subjected to a permanent cold ...

  • Hydroponic cultivation of lettuce (Lactuca sativa) using effluents from primary, secondary and tertiary + UV treatments

    ABSTRACTThe aim of this study was to evaluate the potential cultivation of lettuce (Lactuca sativa) with domestic wastewater effluents with different levels of treatment from a compact WWTP in Brazil. Vegetables were grown in five treatments: nutrient solution (control), secondary effluent diluted 50%, secondary effluent not diluted, tertiary effluent UV irradiated, and UASB effluent. ...

  • Reuse of dairy lagoon wastewater through SDI in forage crops

    Abstract California has become the leading dairy products producing state in the USA. This has resulted in farms commonly milking several thousand cows per day. The care and feeding of the animals has produced large waste streams commonly collected and stored in lagoons. Environmentally safe handling and reuse of the lagooned wastewater is the objective of this study. A system of ...

  • Soil water repellency development in amended sand rootzones

    Particulate organic matter (OM) and surface area–limited sands are associated with soil water repellency (SWR) in turfgrass systems. The increasing ubiquity of amended sand rootzones warrants investigation of factors contributing to SWR. Our objective was to identify how amendment type and/or inclusion rate affect rootzone SWR over a range of irrigation regimes. A U.S. Golf Association–specified ...

  • Scalewatcher Banishes Limescale In Gardens And Greenhouses

    In hard water areas, automated watering systems, sprinkler irrigation systems and greenhouse-misting systems clog with limescale, plant leaves develop white scale deposits and over-spray causes limescale build-up on greenhouse windows. Scalewatcher North America, manufacturers of the original, patented and award-winning computerized electronic water-conditioner, Scalewatcher®, has a range of ...

  • Biopesticides Examined for Role in Field Production

    Biopesticides deserve respect. Once derided as snake oil, today’s products have proven benefits in suppressing pest organisms. Whether they activate plant defenses, parasitize or inhibit pathogen growth or make the environment less favourable to disease, they can play an integral role in crop protection. While the greenhouse sector first excelled at incorporating biopesticides in controlled ...

  • Growth and phosphorus uptake of three riparian grass species

    Riparian buffers can significantly reduce sediment-bound P entering surface water, but control of dissolved P inputs is more challenging. Because plant roots remove P from soil solution, it follows that plant uptake can reduce dissolved P losses. We evaluated P uptake of smooth bromegrass (Bromus inermis Leyss.), reed canarygrass (Phalaris arundinacea L.), and switchgrass (Panicum virgatum L.) ...

  • Integrating ecosystem services into crop protection and pest management: Case study with the soil fumigant 1,3‐dichloropropene and its use in tomato production in Italy

    Ecosystems provide the conditions for producing food, regulating water, and providing wildlife habitats; these, among others, are known as ecosystem services (ESs). Food production is both economically and culturally important to southern European farmers, particularly in Italy where farmers grow flavorsome tomatoes with passion and pride. Growers rely on pesticides for crop protection, the ...

  • Stud case study

    A major vegetable grower in Lantokia, Fiji, using soilless culture systems began to trial Amnite A-100. His crops consisted principally of lettuce, tomatoes, capsicums, cucumbers, zucchinis and melons.
