Abstract The present invention provides non-intergeneric remodeled microbes that are able to fix atmospheric nitrogen and deliver such to plants in a targeted, efficient, and environmentally sustainable manner. The utilization of the taught microbial products will enable farmers to realize more productive and predictable crop yields without the nutrient degradation, leaching, or toxic runoff associated with traditional synthetically derived nitrogen fertilizer, by mitigating or eliminating the need for exogenous nitrogen- containing fertilizers. The remodeled microbes have unique colonization and nitrogen fixation abilities, which enable the microbes to deliver nitrogen to a cereal plant in a spatially targeted ( e.g. rhizospheric) and temporally targeted ( e.g. during advantageous stages of plant's life cycle) manner. The microbes are able to replace the standard agricultural practice of sidedressing and enable a more environmentally sustainable form of farming. The present disclosure also provides methods of using non-intergeneric remodeled microbes, for example, to fix atmospheric nitrogen by reducing or eliminating the need for exogenous nitrogen-containing fertilizers, to increase yield, and to reduce infield variability in the yield.

The present invention is related to a jassid attractant. Specifically, the present invention relates to a jassid attractant composition consisting of synthetic analogs of bacterial-based volatile compounds consisting of alkanes (Eicosane, Tetrapentacontane, Heneicosane, Tetracosane), and a pyrazine (2-Methyltetrahydro- 2H-Pyrazino (1,2-a) Pyrazine-1,4 (3H-5 6H)-dione), or a combination thereof. The present invention relates to a method for preparing a jassid attractant composition comprising synthetic analogs of bacterial-based volatile compounds. Furthermore, the jassid attractant composition along with yellow sticky traps (YST-existing mechanical control method for jassid) enhanced the jassid attraction to a maximum of 197% compared with the control treatment (YST alone). Furthermore, the jassid attractant is cost effective, does not have any harmful effects on soil nutrient availability and soil biology, and is environmentally friendly. It can reduce chemical pesticide usage and insect resurgence in cotton cultivation, thus having wider commercial application prospects in agriculture.

<pre>The present invention relates to innovative biocomposite beads based on phosphogypsum and freeze-dried spirulina, specially designed to be used as a complementary substrate in culture bed systems (Media Bed System). These biocomposite beads are made from a mixture of phosphogypsum and spirulina encapsulated in a sodium alginate matrix, which is gelled by the addition of calcium chloride. The manufacturing process includes steps of drying the phosphogypsum, incorporation into a gelling solution, stirring, microwave irradiation, and formation of beads by gelation. The beads obtained, whose dimensions vary between 1 mm and 1 cm in diameter, are optimized to improve the retention of water and nutrients in cultivation systems, thus promoting the growth of plants, in particular those of the Cucurbitaceae family. The invention also proposes a culture system using these beads, offering increased efficiency in the assimilation of phosphorus contained in phosphogypsum.</pre>

L'invention concerne un procédé de préparation d'un nanoinsecticide à double encapsulation utilisant des nanoparticules de Al₂O₃ combinées à l'extrait et au marc de la plante Nerium Oleander. Le procédé comprend les étapes de solubilisation d'un polymère à dégradation rapide, le PLGA, dans un solvant apolaire, suivi de l'incorporation des nanoparticules de Al₂O₃ synthétisé à partir de l'extrait de Nerium Oleander pour former une première émulsion. Cette émulsion est ensuite dispersée dans une phase aqueuse stabilisée avec du PVA pour créer des microparticules encapsulant l'agent actif. La deuxième couche est formée en enrobant ces microparticules dans une solution de polymère à dégradation lente, à base d'amidon dissous dans un solvant polaire. Les particules enrobées sont ensuite dispersées dans une phase aqueuse stabilisée avec le marc de Nerium Oleander, avant évaporation du solvant pour former les microparticules à double encapsulation. Ce procédé permet une libération contrôlée et progressive du nanoinsecticide, avec une première couche se dégradant après une semaine et une seconde couche après deux semaines, offrant ainsi une protection prolongée contre les nuisibles.
