28503 results about "Pesticide" patented technology

Pesticides are substances that are meant to control pests, including weeds. The term pesticide includes all of the following: herbicide, insecticides (which may include insect growth regulators, termiticides, etc.) nematicide, molluscicide, piscicide, avicide, rodenticide, bactericide, insect repellent, animal repellent, antimicrobial, and fungicide. The most common of these are herbicides which account for approximately 80% of all pesticide use. Most pesticides are intended to serve as plant protection products (also known as crop protection products), which in general, protect plants from weeds, fungi, or insects.

Mist Generator and Mist Emission Rendering Apparatus

[OBJECTS AND PROBLEMS] Relating to a mist generator capable of emitting any of chemical substances used in life, such as perfumes, pharmaceuticals and pesticides, in the form of fog or vapor. An object of the invention is to attain means for efficiently atomizing liquid, means for easily and rapidly switching the type of chemical substance emitted and a compact apparatus of good maintainability. [MEANS FOR SOLVING PROBLEMS] An apparatus comprises an ultrasonic transducer; an ultrasonic propagation medium disposed so as to fill a plane of vibration of the transducer; liquid retaining means disposed so as to be in contact with an end face of the medium; and an ultrasonic focusing reflecting mechanism (concave reflection mirror) disposed in an ultrasonic propagation path, thereby the apparatus attains discharging into air and atomization of the liquid by means of ultrasonic waves. Atomization efficiency is enhanced by the use of an ultrasonic reflection tube, and mist emission is carried out. Use is made of a compact liquid container equipped at its bottom with an ultrasonic transmission membrane. Various types of liquids can be atomized by changing the direction of ultrasonic course. Mist can be emitted by means of a thermal current as heating means. IC tag is attached to the liquid retaining means or liquid injection means.

Apparatus and process for mediated electrochemical oxidation of materials

A unique apparatus unique apparatus and process that uses mediated electrochemical oxidation (MEO) for: (1) Destruction of: a) nearly all organic solid, liquid, and gases materials, except fluorinated hydrocarbons; b) all biological solid, liquid, and gases materials; c) and/or dissolution and decontamination (such as cleaning equipment and containers, etc.) of nearly all inorganic solid, liquid, or gas where higher oxidation states exist which includes, but is not limited to, halogenated inorganic compounds (except fluorinated), inorganic pesticides and herbicides, inorganic fertilizers, carbon residues, inorganic carbon compounds, mineral formations, mining tailings, inorganic salts, metals and metal compounds, etc.); and d) combined materials (e.g. a mixture of any of the foregoing with each other); henceforth collectively referred to as materials. (2) Sterilization/disinfection of equipment, glassware, etc., by destroying all existing infectious materials. (3) Dissolution of transuranic/actinide materials and/or destruction of the oxidizable components in the hazardous waste portion of mixed waste. (4) Generation of hydrogen and oxygen from MEO of materials. (5) Alteration of organic, biological, and inorganic materials by MEO to produce other compounds from these materials. The materials are introduced into an apparatus for contacting the materials with an electrolyte containing the oxidized form of one or more reversible redox couples, at least one of which is produced electrochemically by anodic oxidation at the anode of an electrochemical cell. The oxidized forms of any other redox couples present are produced either by similar anodic oxidation or reaction with the oxidized form of other redox couples present and capable of affecting the required redox reaction. The oxidized species of the redox couples oxidize the materials molecules and are themselves converted to their reduced form, whereupon they are reoxidized by either of the aforementioned mechanisms and the redox cycle continues until all oxidizable material species, including intermediate reaction products, have undergone the desired degree of oxidation. The entire process takes place at temperatures between ambient and approximately 100° C. The oxidation process may be enhanced by the addition of reaction enhancements, such as: ultrasonic energy and/or ultraviolet radiation.

System for uniform dispersal of agricultural chemicals

A system for uniformly dispensing agricultural chemicals in soil comprises a holding reservoir for the liquid agrichemicals, at least one multi-port uniform dispersing manifold or splitter, and a number of dispensing delivery tubes for dispensing the chemicals proximate openings or slits in the soil during various functions such as planting. The liquid agricultural chemicals, within the system, flow, under pressure, from the reservoir to the exit orifice of each delivery conduit. The multi-port, uniform liquid dispersing manifold passively equally and uniformly, divides the incoming fluid stream to provide separate, but substantially equal, divided fluid streams exiting the manifold to individual delivery conduits. The fluid stream flowing through the fluid inlet of the manifold, under pressure, impinges a planar surface, disposed at one end of the manifold inlet, substantially perpendicular to the fluid flow and proximate the manifold exits, such that the fluid stream is radially dispersed and uniformly divided among the exit ports of the manifold. Advantageously, the fluid exit ports which are radially disposed about the fluid inlet have a longitudinal axis substantially perpendicular to the fluid flow in the fluid inlet causing the direction of the exit a flow to be substantially perpendicular to the fluid flow in the fluid inlet.

Soil fertility amendment and preparation method thereof

The invention provides a multifunctional soil nutrient conditioner formula with low cost, practicality and effectiveness and a preparation method thereof aiming at the technical problems. The production technology is simple, the production cost is low, and no harmful gas and sewage are generated during production. The product can effectively provide dozens of nutritive elements required for plant growth, is applied by being combined with a common fertilizer and an organic fertilizer, and can obviously improve the utilization rate of the fertilizer, so as to reduce the fertilizer input; and simultaneously the product can obviously stimulate action of beneficial floras of the soil, inhibit action of causal organisms, and increase the disease suppression of the soil and the resistance of plants, and then can effectively control generation of physiological diseases and soil-borne diseases, so as to reduce the pesticide input. The fertilizer input and the pesticide input can be reduced by more than 15 to 30 percent, and the yield can be increased by more than 15 to 30 percent, and simultaneously the product quality is obviously improved and cost conservation and synergism are obvious. Moreover, the soil improvement effect is obvious, and the sustainable utilization capacity can be obviously enhanced.

Process of converting rendered triglyceride oil from marine sources into bland, stable oil

Triglyceride oil derived from marine sources, mammalian and fish, is treated with a silica at relatively low temperature under vacuum and is then further treated with a bleaching clay under vacuum and at higher temperature. The silica and the bleaching clay are then separated from the oil. The oil treated by this method is essentially free of proteinaceous materials, phosphatides and mucilage, pro-oxidant metals and very low in colored compounds, and is suitable for deodorizing. The deodorized oil is completely bland, unchanged in the concentration of the long-chain highly unsaturated fatty acids (EPA, DPA and DHA), very low in color, peroxides and secondary oxidation products, free of pesticides and has very good flavor stability. The method avoids the use of any chemicals, such as in the acid and base treatments required in conventional degumming and alkali refining of oils of marine origin. This avoids the formation of artifacts in the oil and trace contamination with chemicals. It also reduces the number of process steps required to produce deodorized food oil from marine sources, which is advantageous in respect to oil quality, process losses and processing costs. The method is especially environmentally advantageous, since it avoids the need for soapstock and waste water processing entirely. Refined oil produced by the method is useful as a nutritional supplement and in methods of therapy or medical treatment.
