Definitions

  • the present invention relates to compositions and methods for controlling fungi on growing plants.
  • the invention is embodied in compositions and methods for controlling powdery mildew on growing plants.
  • Pyridazinone derivatives such as those disclosed in U.S. Patent No. 4,877X87 to Taniguchi et al (the entire content of which is expressly incorporated hereinto by reference) are well known insecticides to treat crop plants. It has now been discovered that such pyridazinone derivatives may be usefully employed as fungicides when applied to the locus of growing plants in fungicidally effective amounts.
  • compositions are preferably applied to above ground portions of the plants.
  • the application of liquid and particulate compositions to above ground portions of plants may be carried out by conventional methods, for example, boom and hand application, including sprayers or dusters.
  • the compositions may be applied aerially as a spray, if desired.
  • the compositions employed in the practice of the present invention are most preferably used in the form of aqueous solutions that may be applied in a conventional manner, for example, by spraying, atomizing or watering the locus of the plant.
  • compositions of this invention may also be applied in conjunction with other ingredients or adjuvants commonly employed in the art.
  • ingredients include drift control agents, defoaming agents, preservatives, surfactants, fertilizers, phytotoxicants, herbicides, pesticides, insecticides, fungicides, wetting agents, adherents, nematicides, bacteri- cides, trace elements, synergists, antidotes, mixtures thereof and other such adjuvants well known in the art.
  • the assay was performed in three replications.
  • the assay was performed in ten replications. Fourteen days later, grape leaves and rose leaflets were evaluated for percent leaf surface area covered by sporulating powdery mildew. The results appear in Table 1 below versus the results for untreated control (UTC) .
  • Rooted grape cuttings variety Carignane, were sprayed to run off in a spray chamber with kresoxim methyl (BAS 490), pyridaben (BAS 300) or combinations of both as noted below in Table 2. After the plants had dried, they were replaced into the greenhouse and then exposed to conidia of U. necator. Disease development was evaluated 19 days after treatment by estimating the percent area of the treated leaves covered with powdery mildew. The values expressed in Table 2 below are the mean of at least three leaves each on five different plants.
  • Detached leaves of grape (vitis vinifera L. ) and climbing rose (Rosa sp . ) were disinfected by rinsing for 30 seconds in 1.5% hy- pochlorite solution and rinsed with sterile water four times.
  • the leaves were dried and after 24 hours sprayed with either one of a concentration range of kresoxim methyl (BAS 490) , pyridaben (BAS 300) or a mixture of both, dissolved in sterile water to which 0.05% Tween 20 spray adjuvant was added. After 24 hours, the leaves were inoculated by dusting grape or rose powdery mildew conidia, respectively, over the leaf surfaces.
  • grape powdery mildew For grape powdery mildew, the assay was performed in three replications. For rose powdery mildew, the assay was performed in ten replications. Fourteen days later, grape leaves and rose leaflets were evaluated for percent leaf surface area covered by sporulating powdery mildew.
  • pyridaben was applied alone at concentrations between 5 and 320 mg/L. Kresoxim-methyl was tested alone at 5 and 10 mg/L. The mixtures of pyridaben and kresoxim-methyl were tested at 5+5 and 10+10 mg/L.

Abstract

Pour éliminer des champignons sur des plantes de culture on administre à un endroit d'une plante nécessitant un traitement fongique, une quantité efficace du point de vue fongicide d'un dérivé de pyridazinone. De manière plus préférée, le dérivé de pyridazinone est du pyridabène.
