Definitions

  • the present invention relates to pesticidal compositions and processes related
  • Pests such as whiteflies, mites, aphids, scale insects, thrips and mealybugs, cause millions of dollars of damage each year to ornamental plants and plants grown in greenhouses (also known as glasshouses).
  • Some major challenges to greenhouse production and profitability are insects, diseases, and weeds.
  • a major concern for most greenhouse owners is insect resistance to pesticides. Numerous factors have lead to resistance of pesticides. These include pest biology, the intensity of past and present chemical use, aspects of the greenhouse setting, and commercial production practices.
  • whiteflies such as Trialeurodes vaporariorum
  • Trialeurodes vaporariorum are difficult insects to control, especially in greenhouses. The immature stages are small and difficult to detect. Once inside a greenhouse, whiteflies develop and when adults emerge, they quickly become distributed over an entire crop or move to other available host plants.
  • Trialeurodes vaporariorum is commonly known as the "greenhouse or glasshouse whitefly.” It is a primary pest of many fruit, vegetable, and ornamental crops, frequently being found in protected horticultural environments.
  • loss of nutrients by the plant due to sap consumption by the whiteflies may result in growth deformation, yield reduction, wilting of leaves, or death of the plant.
  • the consumption of sap by the whiteflies leads to excretion of excess liquid that contains large amounts of sugar, often referred to as "honeydew.”
  • honeydew As the plant becomes covered in honeydew, a black fungus may grow and cover the leaves so completely that it interferes with the proper physiological activities of the plants.
  • the term “pest” means organisms in the Phylum Arthropoda.
  • the term “pesticide,” means any substance that may be used to control organisms in the Phylum Arthropoda.
  • control and “controlling,” mean killing, eradicating, arresting in growth, inhibiting, reducing in number, and/or imparting sterility.
  • insecticide means a pesticide used for controlling insects.
  • locus means a particular position, point, or area.
  • the term “synergistic” means a combination of components wherein the activity of the combination is greater than the sum of the individual activities of each component of the combination.
  • wt% means a percent of a particular component by weight in a composition based on an overall weight of a composition.
  • the pesticidal compositions herein comprise: (a) spinosad, or spinetoram, or both spinosad and spinetoram; and (b) codacide oil, or savona, or both codacide oil and savona.
  • the pesticidal processes herein comprise: a process to control pests in a locus where control of such pests is desired said process comprising applying a pesticidal composition in an amount effective to control said pests wherein said pesticidal composition comprises (a) spinosad, or spinetoram, or both spinosad and spinetoram; and (b) codacide oil, or savona, or both codacide oil and savona.
  • the combination of ingredients in the pesticidal composition may result in a synergistic effect providing the pesticidal composition with improved efficacy.
  • Such pesticidal compositions may be particularly effective against greenhouse pests, such as Trialeurodes vaporariorum.
  • the pesticidal compositions provide improved efficacy against pests, such as whiteflies, mites, aphids, scale insects, thrips, and mealybugs. It has been found that combining spinosad and/or spinetoram, with codacide oil and/or savona provides a pesticidal composition having improved efficacy against pests (e.g., whiteflies) in comparison to any such components alone. At least one pesticidally-acceptable carrier, solvent, or diluent, may additionally be included in the pesticidal composition to facilitate delivery.
  • Spinosad can be obtained from Dow AgroSciences LLC under the trade names SPINTOR® Insecticide, TRACER® Insecticide and ENTRUST® Insecticide.
  • Spinetoram can be obtained from Dow AgroSciences LLC under the trade names DELEGATE® Insecticide and RADIANT® Insecticide.
  • Codacide Oil can be obtained from Microcide Ltd., Shepherds Grove, Stanton, Bury St. Edmunds, Suffolk IP31 2AR, UK. Codacide Oil is in large part rapeseed oil that has been formulated with plant-based emulsifiers.
  • Savona insecticidal soap can be obtained from Koppert BV, Veilingweg 14, 2651 BE Berkel en Rodenrijs, The Netherlands. Savona is in large part a mixture of naturally occurring potassium salts of fatty acids and alcohols.
  • the pesticidal composition may additionally include one or more ingredients, such as a carrier, a solvent, or a diluent.
  • solvent can be any chemical compound whose molecules contain a hydroxyl group bonded to a carbon atom, such as, for example, methyl alcohol or ethyl alcohol.
  • the solvent can be water, propylene glycol, glycerol, ethyl alcohol, isopropyl alcohol, methyl alcohol, tetrahydrofufuryl alcohol, oils, and combinations thereof.
  • a variety of other ingredients may be added to the pesticidal composition.
  • the pesticidal composition may additionally include preservatives, surfactants, adhesion promoters, solubilizers such as oleic acid or lactic acid, viscosity modifiers, UV blockers or absorbers, colorants, and stabilizers, such as antioxidants.
  • preservatives such as surfactants, adhesion promoters, solubilizers such as oleic acid or lactic acid, viscosity modifiers, UV blockers or absorbers, colorants, and stabilizers, such as antioxidants.
  • the components of the pesticidal composition can be mixed together in any conventional manner.
  • a backpack sprayer has been used.
  • the amount of spinosad to use in the pesticidal composition is generally about 0.02 to about 0.3 grams per liter (g/L) of carrier. In another embodiment of this invention about 0.04 to about 0.2 g/L can be used. In another embodiment of this invention about 0.06 to about 0.1 g/L is used.
  • the amount of spinetoram to use in the pesticidal composition is generally about 0.01 to about 0.2 g/L of carrier. In another embodiment of this invention about 0.02 to about 0.1 g/L can be used. In another embodiment of this invention about 0.03 to about 0.8 g/L is used.
  • the amount of codacide oil to use in the pesticide composition is generally from about 1 part by volume codacide oil to about 600 parts by volume carrier, although a larger or smaller ratio can be used, such as 1 part codacide oil to 900 parts carrier or 1 part codacide oil to 300 parts carrier.
  • the amount of savona to use in the pesticidal composition is generally from about 1 part by volume savona to about 50 parts by volume carrier, although a larger or smaller ratio can be used, such as 1 part savona to 100 parts carrier or 1 part savona to 25 parts carrier.
  • the amount of pesticidal composition to be used to control pests in a locus depends on many factors, such as the particular pests or the resistance of such pests to pesticides, to name a few factors. However, in general, about 1500 liters per hectare (L/ha) of pesticidal composition may be used, although more or less can be used, such as about 1000 L/ha or about 2500 L/ha.
  • L/ha liters per hectare
  • the pesticidal compositions may be applied directly to, or to a surface adjacent to, a locus which includes a population of undesirable pests.
  • the pesticidal compositions may be applied using a sprayer to foliage of plants in a greenhouse.

  • Composition 3 and 6 were made by mixing the insecticide and codacide oil first to form a premix and then mixing with water to form a mixture that can be used in a backpack sprayer.
  • Each composition was tested in two glasshouses in separate geographical settings ("Site A” and "Site B”). Each glasshouse had separate 3 square meter (m 2 ) plots in which each composition could be tested. Each composition was tested in 4 plots in each glasshouse. In each plot, glasshouse tomatoes were planted and allowed to grow to stage 72 (see BBCH-scale (solaneous fruit)) before they were infested with nymphs of Trialeurodes vaporariorum, which is also commonly known as the
  • Trialeurodes vaporariorum nymph population were carried out at 0, 3, 7 and 14 days after application (DAA). At each assessment, ten (10) leaves were selected from each plot and examined thoroughly under a stereoscope. The number of live Trialeurodes vaporariorum nymphs on each of these leaves was determined. Subsequently, the population in each plot was expressed as the total number of live nymphs per ten leaves. The least significant difference (LSD) test at a probability level of 0.5 was used to compare the means. Percent control of
