  • Method for controlling yellow nutsedge using Puccinia canaliculata
    Patent number: 4731104
    Abstract: A biological method for either controlling or eliminating yellow nutsedge in agricultural fields is disclosed. An agricultural field which contains yellow nutsedge is inoculated with a sufficient amount of an effective strain of rust fungus Puccinia canaliculata and a carrier to an epidemic. As a result of reducing competition from the yellow nutsedge and inhibiting reproduction, the yellow nutsedge is either controlled or eliminated. Best results occur when the agricultural field is inoculated in the spring of the year. Application methods include: spraying, granular, irrigation, wind-carried, or air-dropped.

  • Combination fertilizer composition
    Patent number: 4704160
    Abstract: Nitrogen containing fertilizers are combined with a plant growth regulator, of the type which retards gibberellin synthesis in plants, in a ratio of nitrogen to plant growth regulator of at least 40 to one. The resulting combination fertilizer composition, when applied to vegetation at the rate of 0.006 to 0.6 pounds per acre of plant growth regulator, delivers nutrients to plants in a fashion that more closely approximates their needs than any previously known plant nutrient compositions. Preferred plant growth regulators which operate by retarding gibberellin synthesis are paclobutrazol and flurprimidol which may be used as the only plant growth regulator in the combination fertilizer composition or together with a very small amount of a second plant growth regulator, such as mefluidide.
