Definitions

  • the present invention is directed to methods of reducing insect-vectored viral infections and transmission in plants, in particular grass (Poaceae) plants, more particular cereals, methods of reducing damage to plants caused by viral infection, methods of crop enhancement including methods for improving plant growth, vigour and yield, by application of a seed treatment comprising at least one plant activator, to compositions comprising the combinations and to plant propagation material treated therewith.
  • the present invention provides a method of reducing insect-vectored viral infection in a plant, plants of the crops: grass crops including, but not limited to, cereals (wheat, barley, rye, oats, maize, rice, sorghum, triticale and related crops); leguminous plants (beans, lentils, peas, soybeans); oil plants (rape, mustard, canola, sunflowers); cucumber plants (marrows, cucumbers, melons); fibre plants (cotton, flax, hemp, jute); vegetables (spinach, lettuce, asparagus, cabbages, broccoli, cauliflower, carrots, onions, tomatoes, peppers, potatoes, paprika); as well as ornamentals (flowers, shrubs, broad-leaved trees and evergreens, such as conifers, also including transgenic crop plants of the foregoing types.
  • grass crops including, but not limited to, cereals (wheat, barley, rye, oats, maize, rice, sorghum, triticale
  • increasing the yield of a plant means that the yield of a product of the plant is increased by a measurable amount over the yield of the same product of the plant produced under the same conditions, but without the application of the combinations according to the present invention. It is preferred that the yield is increased by at least about 0.5%, preferably 1%, more preferably 2%, yet more preferably 4% or more. Even more preferred is an increase in yield of at least about 5%, 10%, 15% or 20% or more.
  • an 'improved tolerance to stress factors' means that certain traits are improved qualitatively or quantitatively when compared with the same trait in a control plant which has been grown under the same conditions in the absence of the method of the invention.
  • Such traits include, but are not limited to, an increased tolerance and/or resistance to abiotic stress factors which cause sub-optimal growing conditions such as drought (e.g. any stress which leads to a lack of water content in plants, a lack of water uptake potential or a reduction in the water supply to plants), cold exposure, heat exposure, osmotic stress, UV stress, flooding, increased salinity (e.g. in the soil), increased mineral exposure, ozone exposure, high light exposure and/or limited availability of nutrients (e.g.
  • Gemini viruses possess single- stranded circular DNA genomes, falling into three genera, i.e. the leafhopper-transmitted Mastreviruses, such as maize streak virus, MSV; and the whitefly-transmitted Begomoviruses, such as bean golden mosaic virus, BGMV.
  • Increased yield of an agricultural plant means that, where it is possible to take a quantitative measurement, the yield of a product of the respective plant is increased by a measurable amount over the yield of the same product of the plant produced under the same conditions, but without application of the present invention. According to the present invention, it is preferred that the yield be increased by at least 0.5%, more preferred at least 1%, even more preferred at least 2%, still more preferred at least 4% , preferably 5% or even more.
