4632936 INSECTICIDAL COMPOSITIONS Clive Boase, Howard B Dawson, Sawston, United Kingdom assigned to FBC Limited The persistance of bendiocarb and propoxur deposited on both porous and non-porous surfaces is increased by the addition of silica to formulations, in which the insecticides are dissolved in organic solvent.
4632938 THIOPHENYLUREAS, THEIR PRODUCTION AND USE Hirosh Nagase, Yasuo Sato, Kawanishi, Japan assigned to Takeda Chemical Industries Ltd New insecticidal or/and ovicidal benzoylurea derivatives of the formula: See Patent for Chemical Structure wherein XI is hydrogen or halogen; X2 is halogen; YI, Y2 and Y3 are hydrogen, halogen or alkyl, whereby at least one of Y1, Y2 and Y3 is other than hydrogen; and R is hydrogen or a group represented by the formula -CFaZbH(3-a-b) wherein a and b are 0, 1, 2 or 3, with a + b ( or = 3 and Z is halogen, their production and use.
8605806 INFECTIOUS BRONCHITIS VIRUS SPIKE PROTEIN Matthew McKinley BINNS, Michael Edward Griffith BOURSNELL, Thomas David Kay BROWN, Fiona Margaret TOMLEY, Appleby Cottage, Earith Road, Colne, Huntingdon, Cambridgeshire PEI 7 3NJ, United Kingdom assigned to NATIONAL RESEARCH DEVELOPMENT CORPORATION The problem of diagnosis and typing of infectious bronchitis virus in poultry has been solved and important progress made towards an IBV vaccine by this invention. DNA complementary to the region of genomic 1BV RNA which codes for a spike protein polypeptide comprising the SI polypeptide (containing antigenic determinants) or the $2 polypeptide (containing means for anchoring the spike protein to the viral membrane) has been made. It can be carried by a cloning vector, incorporated in a host and cloned. It can also be cloned in a poxvirus which is used to transfect mammalian cells. Such cells express an artificial spike protein polypeptide.

VACCINE
Dennis Leslie WATSON, 14 Sunset Avenue. Armidale, NSW 2350, Australia assigned to COMMONWEALTH SCIENTIFIC AND INDUSTRIAL RESEARCH OR A killed vaccine effective in the immunisation of ruminants against intramammary challenge by S.aureus, comprises antiphagocytic in vivo antigen(s) produced by a pseudocapsule-producing strain of S.aureus. An in vitro method of cultivating S.aureus under "simulated in vivo conditions" is also disclosed, together with methods for the production and use of the killed vaccine.
8607235 METHOD AND ACTIVE FILTER ELEMENT FOR PREVENTING THE DEVELOPMENT OF PLANTS Philippe GRAVISSE, 18-20, rue des Presles, F75015 Paris, France The invention relates to agriculture. More particularly it relates to a method for preventing the development of plants on a cultivation area exposed to a natural or artificial light radiation characterized in that it comprises the elimination in the spectrum of light radiation of at least one of the two bands of wave lengths which favour the photosynthesis and which are situated the first one between 4200 A ) o and 4900 A)o and the second band between 6000 A ) o and 7000 A)o. It also relates to an active filter element for implementing such method according to the present invention, which filter element is characterized in that it is comprised of a plastic material sheet containing dispersed therein at least one luminescent and/or fluorescent material forming a luminous cascade to absorb the incident radiation of at least one of said two bands of wave lengths for reemitting it into an emission band of different wave lengths, covering wave lengths which unfavour or hinder the photosynthesis of plants. The invention applies particularly to the soil cover which prevents the development of plants.
