A barrier assembly including a bracket member (10) with a base (14) and an inclined upper part (16). An alignment adaptor (36) may be provided which mounts the bracket (10) at an inclination to a mounting surface for instance for use in corners. The bracket member 10 may be mounted on an extension member (68) which enables the bracket member to extend higher than would otherwise be the case.

A repellent delivery device may include a body having a hygroscopic base material, and one or more of an insecticide, and an insect repellant. The repellent delivery device may have a support structure coupled between the body and a trunk of a plant. The body may be configured to release the one or more of the insecticide and the insect repellant into a root ball of the plant using ambient moisture.

A plant cover apparatus includes a bag having an interior encompassed by a wall that extends from a top end of the bag and tapers inwardly to a bottom end of the bag. The bottom end includes a rim that laterally circumscribes a plant-receiving opening formed through the bag. The bag has a slot that extends vertically from the opening through the wall. The slot includes opposed margins having cooperatively interlocking parts that can temporarily be joined and separated to increase the size of the opening. The bag may be vertically suspended from a support member positioned next to the plant. An exterior perimeter of the bag may be rigid enough to help the bag maintain its shape when suspended.

A netting material is knitted from at least two synthetic material yarns of which one is an opaque and the other is a transparent or translucent or different opaque yarn. A knitted netting material comprises a plurality of primary yarns knitted to form a mesh construction having an arrangement of primary apertures defined by yarn intersections and yarn connecting portions between yarn intersections, and a plurality of secondary yarns crossing over the primary apertures to form secondary apertures within the primary apertures.

An insect barrier system configured for positioning about a tree trunk. The system includes a barrier member having an extending portion which includes an inner edge extending along a plane and an outer edge positioned a distance from the plane. The barrier member is configured to be positioned about the tree trunk such that the inner edge is in sealing engagement therewith and a containment area is defined between the extending portion and the tree trunk. A collection sack is configured to be positioned above the barrier member. A tunnel member having a passage therethrough is positioned such that an inlet opening thereof opens into the containment area and on outlet opening thereof opens into the collection sack.

An insect barrier strip that prevents targeted insects from climbing up a targeted tree. The insect barrier strip may contain insecticides that the targeted insects will encounter and kill. The insect barrier strip may be made of material(s) with a low coefficient of friction to provide a difficult surface for insects to traverse, that are flexible/expandable to enable the insect barrier strip to be wrapped around a tree trunk and expand over time as the trunk grows, are chemical resistant so insecticides will not degrade, and are capable of withstanding a wide range of environmental conditions. The insect barrier strip may include an overhang to make it more difficult for the targeted insects to get past. The insect barrier strip may include a trough that the insecticide can be located in or clips that insecticide can be secured to. A wick can be utilized to hold the insecticide.

A method and system for eradicating insects in palm trees (such as arecaceae) by means of a lower stem encasement embedded with fumigant. Said encasement comprised of a plastic, polymer sheet with internal, flexible foam lining. The lining having a plurality of apertures configured to receive a multitude of fumigants (such as aluminum phosphide tablets) therein. The invention being wrapped around the perimeter of the aforementioned palm tree and selectively affixed by means of adhesive strips and adjustable strapping on distal ends. While it is well-known that such insects respond well to fumigants, it is difficult to make contact with them in the center of a tree. An object of the invention is to impregnate an Arecacae tree with fumigants by means of a non-invasive fumigant wrap system.

Methods and platforms are provided for maintaining a population of natural enemies on plants, prior and/or parallel to an occurrence of respective prey pests, by associating with the plants platform(s) comprising mechanical support(s) with attached feeding elements for the natural enemies. The platform may be configured to keep the feeding elements close to but not on the plants, protecting them and enhancing the distribution efficiency and life time, while maintaining good availability of the feeding elements to the natural enemies. Various features may enhance supporting the natural enemies' population prior and/or parallel to the occurrence of the pest prey such as olfactory and/or visual cues to the feeding elements as well as sheltering elements such as artificial domatia on the surface of the mechanical supportto enhance biological pest control. Moreover, methods for preparing decapsulated Artemia cysts as feed for predatory arthropods are provided.

An enclosing plant sheath for encircling and protecting a plant stem or vine, which may be joined with other similar sheaths, to create a beneficial microenvironment for developing plants.

A netting material having a length dimension and a width dimension much smaller than the length dimension is formed by threads knitted or woven together. The netting material has a main portion comprising knitted or woven apertures, a reinforced edge portion at or adjacent each longitudinal edge of the netting material comprising a longitudinal row of knitted or woven fastening features, and a reinforced intermediate portion between the reinforced edge portions. The reinforced intermediate portion has a first longitudinal row of knitted or woven fastening features and a corresponding second longitudinal row of knitted or woven fastening features. In use, the netting material is folded so that the first longitudinal row of fastening features and the second longitudinal row of fastening features are brought together to form a double-layered row of fastening features. The double-layered row of fastening features and the row of fastening features of the reinforced edge portions provide three longitudinal attachment locations for securing the netting material to a support structure.
