Provided is a sustained-release pheromone preparation that can be easily installed and stably retained in an installation location, and is comprised of at least one pheromone substance-containing polymer tube with both ends sealed or pheromone substance-containing polymer rod, wherein (a) a closed space is formed in a front view by bending in an arc and crossing the tube or rod, and the preparation is not crossed in a side view; (b) a curvature radius established is 4 to 17 mm; (c) a linear distance from a top point of an arc to a crossover point is 25 to 70 mm; and (d) a repelling force when opening the crossover point to establish a clearance of 20 mm in the front view is 0.5 N or larger.

A device insertable inline in a condensation drain line for preventing algae “plugs” from forming in the drain line. The device has an inlet, an outlet and a reaction chamber therebetween. A charge of algaecide is positioned with respect to the floor of the reaction chamber in a feed channel so that, as condensate enters the inlet of the reaction chamber and is diverted toward the algaecide the algae in the condensate can be killed. Additional flow diverters apply backflow to retain the condensate in contact with the algaecide momentarily before the condensate exist the device and is discharged to the environment.

A composition is disclosed including combining a carbonate or bicarbonate compound, an acid, a biostimulant, a nutrient, and a pesticide. The composition may be processed into a tablet, powder, meal, pellets, or granules and produce effervescence when a liquid, such as water or a water-based liquid is mixed with the composition.

Present invention teaches the method of using a keratin hydrolysis peptide (KHP) solution to enhance the yield and quality of tea leaves. By selectively choosing specific weights of feathers and water, and treating the mixture to a high-temperature high-pressure hydrolysis process, the resulting solution is confirmed to contain at least 253 peptides and then apply to the tea trees either by infusing to the soil or by leaf spray at certain growth stages. Optionally, the KHP solution can be diluted by water, as disclosed in the specification, for soil infusing or leaf spraying.
