INSECTICIDAL HYBRID BACTERIA FROM B.T. KURSTAKI AND B.T. TENEBRIONIS Dimitri Karamata, Jean-Christophe Piot, Epalinges, Switzerland assigned to Sandoz Ltd The invention provides hybrid microorganisms comprising the gene coding for b.t. kurstaki delta-endotoxin and the gene coding for b.t. tenebrionis delta-endotoxin, their preparation, insecticidal compositions comprising such microorganisms and their use. 4798723 AGRICULTURAL PRODUCTS FROM PSEUDOMONAS CEPACIA STRAINS AND METHODS OF PREPARATION Peter J Dart, K Prakash Hebber, Fadden, Australia assigned to Lubrizol Genetics Inc Agricultural methods of biological control and organisms useful in such methods are disclosed, such as a plant colonizing organisms and methods of biologically controlling plant disease caused by fungi. A novel type of Pseudomonas cepacia type Wisconsin has been identified. These strains and other P. cepacia strains described are useful as vectors for delivery to plants of beneficial products.

4803803 GROWING MEDIUM PLANTS

FOR

Frank Moffet The present invention provides a plant growth media which comprises small tufts of mineral wool having dispersed therein, particles of acidic phenolic resin for pH control and particles of vermiculite. The ingredients and structure of the product results in a lightweight growth media having a suitable pH for growing certain plants while also providing for flowability, enhanced water adsorption and cohesiveness which prevents the composition from spilling out of Certain types of plant containers. The composition also provides enhanced root anchorage without sacrificing the properties of flowability and

water adsorption. The-composition also optimizes other features which makes the composition and ideal plant growth media.

4804624 PASSIVE AGGLUTINATION ASSAY FOR PSEUDORABIES ANTIBODY Preston H Dorsett assigned to The University of Tennessee Research Corporation A latex agglutination assay to detect antibodies against pseudorabies virus is provided. The test assays swine serum or plasma for the presence of pseudorabies virus antibody which is indicative of an acute or previous infection or vaccination. The latex reagent is a suspension of latex particles, 0.9 microns in diameter, that have adsorbed thereon antigens from disrupted and solubilized pseudorabies virus. When this material is mixed by rotation with serum containing pseudorabies antibodies, the latex will agglutinate forming visible clumps. In the absence of antibody, the latex suspension will remain smooth "and evenly dispersed.

4806483 PROCESS

FOR REGENERATING CORN

Andrew S Wang assigned to Sungene Technologies Corporation The invention is directed to a process for regenerating plants from mature corn embryos. The process comprises the steps of culturing the mature embryo on a callus induction medium to induce callus, subculturing the callus on a maintenance medium to maintain the callus, and subculturing the maintained callus on a regeneration medium to produce plants.
