Definitions

  • This invention relates to compounds that can induce resistance to plants to ward off fungal, bacterial, viral and insect infestations.
  • Fertilizer are added to soil or sprayed on leaves to supply nutrients to grow crops.
  • Phosphorus needed by plant is applied today in many forms. They are either phosphate salts derived from phosphoric acid or phosphite salts derived from phosphorous acid or the acids themselves.
  • Phosphate fertilizers have been on the market for several decades and phosphite fertilizers have been on the market in Australia and Europe since 1990. Phosphites to be used as fungicides was also patented as early as 1978 by Patent No. 4075324.
  • Phosphorous acids have been used to fertilize soils and plants in Australia from 1980's. So phosphorous acids in themselves and salts of these acids called phosphites or phosphonates (Whiley et al; 1992) have been in use since 1990's and their use as fertilizers are in public domain. Fungicides, bactericides and insecticides have been applied since the 1950' s to control fungi, bacteria, insects and nematodes that attack the plants. These chemical pesticides are not only contaminating the environment, pose a danger to workers, leave traces of pesticides in the produce consumed, but are also becoming quite useless as these pathogens are fast developing resistance to these chemical agents.
  • fertilizers containing potassium, calcium, magnesium, manganese, zinc, copper, iron and sodium have been used as fertilizers for several decades in many forms of salts and these fertilizers are also in public domain.
  • U. S. Patent 6,372,238 discloses a process for implanting dry implant sticks into banana and plantain plants for providing nutrients and improving resistance to plant pathogens. The nutrient was slowly released over time and the implant provided reduction of infection by certain pathogens. However, the implant did not obtain the result of the composition of the present invention.
  • An object of this invention is to provide a systemic inducer for plants including a nutrient material and live bacterial, fungus and viruses or a bacterial, fungal or viral extracts for inducing systemic resistance in plants to diseases such as downy mildew (plesmopara viticola), phytopthera, pythium, black and yellow sigatoka and resistance to insects.
  • a systemic inducer for plants including a nutrient material and live bacterial, fungus and viruses or a bacterial, fungal or viral extracts for inducing systemic resistance in plants to diseases such as downy mildew (plesmopara viticola), phytopthera, pythium, black and yellow sigatoka and resistance to insects.
  • the nutrients or fertilizers are phosphoric acids, phosphorous acids, phosphates, phosphites, salts of calcium, magnesium, potassium, managanese, zinc, copper, iron and sodium.
  • Microorganismic substances alive or in an extracted or hydrolyzed form is combined with the fertilizer material and applied to the plants to provide the systemic resistance to plant diseases.
  • the systemic inducer may be applied to the stem, leaves, flowers or fruits of plants. Alternatively, the systemic inducer may be applied to soil to elicit induction into the plants via the roots of plants. Finally, the systemic inducer may be injected into the stem or pseudo stem of the plant.
  • Plants have the ability to ward off infections by fungal, bacteria, virus and insects to a certain degree. Some varieties have natural resistance built in to ward off severe infections and some varieties do not have this ability.
  • systemic acquired resistance Any material that is applied to plants for plants to develop resistance is called “inducers”. So applying certain, inducers can elicit certain plants to develop systemic resistance. This is a new field of investigation and development.
  • the closest parallel process is akin to a human developing resistance to a particular disease after being vaccinated.
  • Simple salts such as phosphites, phosphates, oxalates and salicylates are known to provide a small degree of immunity to plants.
  • the present invention provides a systemic resistance inducer that is obtained by combining a phosphorous acid and salts thereof, phosphoric acid and salts thereof and the salts of calcium, magnesium, potassium, zinc, manganese, copper, iron and sodium with extracts of microorganisms.
  • the systemic inducer is applied to plants as a foliar application, or applied to the soil on which the plants are planted or injected into the stem or pseudo stem of these plants.
  • These extracts do not by themselves cause any significant induction or invade the plant as they are not pathogenic ⁇ - -so the . 1.00% effective induction is taking place only when these extracts are used in combination with the fertilizers listed above.
  • Growth enhancers or regulators such as betaine, benzothio diazole, jasmonic acid, cytokinin, auxin and gibberellins, beta amino butyric acid may be combined to relieve the stress caused by the induction program.
  • Salicylates, oxalates, napthaletes have also showed some induction of resistance, but when combined with the nutrients they add to the induction process effectiveness and with increases in productivity.
  • Microorganisms were grown in a medium and allowed to die by attenuating it with formaldehyde or exposing to microwaves or hydrolyzed with acids and the extracts obtained from these organisms were tested for induction of resistance on various plants such as strawberry, apple, citrus, tomato, grapes and banana. These plants thus treated were then challenged by exposing the plants to pathogens such as mildew, phytopthera, black sigatoka and thrips and mites. The plants suffered severe infestation. But when these same extracts were combined with a phosphate or phosphite or calcium nitrate or magnesium sulfate and applied to a new set of plants in the same manner of the application of extracts alone, all plants resisted the infestation of fungal and insects.
  • the specific microorganisms such as pseudomonads tricboderma species, bacillus subtilis rhodotorulum species, xanthomonas species, plant growth promoting Rhyzobacteria such as IN 937b and SE 34 were specifically cultured, hydrolyzed and used as is or in combination with a calcium phosphite, potassium phosphate, calcium citrate on a set of plants.
  • Such plants include lettuce, strawberry, tomato, grapes, banana, blueberry, apples, corn and potatoes.
  • insects such as thrips, mites, Japanese beetle, leaf hopper and blueberry maggot fly while the non-combined product used showed heavy infestation.
  • insects such as thrips, mites, Japanese beetle, leaf hopper and blueberry maggot fly while the non-combined product used showed heavy infestation.
  • potatoes had no signs of infection by rhyzoctonia, phytopthera on tomato, and citrus.
  • insects There were no insects to be found in the traps or on the leaves.
  • Extracts from garlic, tea tree oil (maleluca), vanilla extract, marigold extracts were combined with potassium phosphite and calcium phosphite and used in field trials to evaluate insect resistance by plants.
  • Tomato, banana, apple, grapes, blueberry and the combinations out performed the extracts by themselves or the fertilizer by themselves.

Abstract

La présente invention décrit un agent stimulant systémique comprenant un nutriment associé à une substance extraite de micro-organismes ou d'insectes. Le nutriment ou fertilisant contient un acide et/ou un sel de phosphore, de potassium, de calcium, de sodium, de magnésium, de manganèse, de zinc, de cuivre ou de fer. Ladite substance peut être extraite de champignons, de bactéries, de virus ou d'insectes. Ledit agent stimulant systémique peut être appliqué aux pousses, aux feuilles, aux fleurs ou aux fruits de plantes. Ledit agent peut également être appliqué au sol afin d'induire une réponse systémique via les racines des plantes. Enfin, ledit agent stimulant systémique peut être injecté dans les pousses ou la pseudo-tige des plantes.
