The current disclosure relates to a chemical-free composition that increases the nutritive value of crops, by increasing vitamin levels in the crop produce. The composition disclosed in the current invention also increases crop yield. The composition does not contain any chemicals and can increase vitamin levels in the crop produce by non-transgenic means, which can help to alleviate deficiency diseases due to malnutrition in an inexpensive and sustainable manner.

A slow-release silk thread and a method for preparing the slow-release silk thread are provided. The slow-release silk thread includes a substrate layer, a slow-release layer, and a protective layer. The slow-release layer is provided between the substrate layer and the protective layer. The slow-release layer includes porous microspheric particles in which a functional agent is adsorbed. The slow-release silk thread obtains a composite structure through the method and realizes slow release of the functional agent by taking advantage of an adsorption performance of a special granular powder, thereby prolonging effective duration of the functional agent.

Methods and compositions are provided which employ a silencing element that, when ingested by a pest, such as a Pentatomidae plant pest or a N. viridula, Acrosternum hilare, Piezodorus guildini, and/or Halymorpha halys plant pest, decrease the expression of a target sequence in the pest. In specific embodiments, the decrease in expression of the target sequence controls the pest and thereby the methods and compositions are capable of limiting damage to a plant. The present invention provides various target polynucleotides set forth in any one of SEQ ID NOS: 1-292 or 302-304 or active variants and fragments thereof, wherein a decrease in expression of one or more the sequences in the target pest controls the pest (i.e., has insecticidal activity). Further provided are silencing elements which when ingested by the pest decrease the level of the target polypeptide and thereby control the pest. In specific embodiment, the pest is Pentatomidae. Plants, plant part, bacteria and other host cells comprising the silencing elements or an active variant or fragment thereof of the invention are also provided.
