extract nucleoproteins from said material, adding a sufficient amount of an acid to form a precipitate of nucleoproteic material, and recovering said nucleoproteic material pre- cipitate. A composition of nucleoproteic material produced according to this process. A method for alleviating symptoms of neoplastic diseases which comprises sterilizing the composi- tion of nucleoproteic material, preparing a for- mulation comprising an effective amount of said sterilized composition, and administering said formulation to a patient having symptoms of a neoplastic disease.

Method and composition for an insecticide com- prising a hydrated hydrogel capsule containing an insecticidally effective amount of at least one nematode capable of infecting an insect host, which capsule has sufficient hydration to main- tain the viability and infectivity of said nematode. Also disclosed are methods for pro- viding said insecticidal compositions.

It is the object of the invention to provide a chemical substance which is effective, in par- ticular, against insect-transmitted viruses, com- pared with conventional plant-virus disease preventive agents. This substance is produced from tissues of plants of the genus Mirabilis, and may be widely utilized as a basic protein with anti-plant-virus effects and as an active ingred- ient for plant-virus diseases preventive agents. Such preventive agents can eliminate difficulties in safety, and is effective because antiviral ac- tivity is developed systemically.
