The preparation can effectively save the active ingredients by more than 70 percent, and can be directly applied on the surface of rice paddy field. The preparation has the characteristics of low cost, high efficacy, lasting drug action, safety, convenient use and so on, and is an environment-friendly agricultural chemical preparation.

The invention relates to a mango preserving technology. In order to achieve integrative pre-plucking and post-plucking preserving effect, the invention comprises four composite preserving pretreatment measures of disinfectant and calcium fertilizer spraying before mango plucking and heat treatment, rot-proof film-coating preservative treatment and ethylene inhibitor treatment after the plucking. The rot-proof film-coating preservative comprises 0.25 percent to 2 percent of glucomannan or / and 0.25 to 2 percent of CTS with 95 percent degree of deacetylation, 0.1 to 1 percent of sucrose fatty acid ester or / and 0.1 to 1 percent of glycerel monostearte, 0.1 to 0.5 percent sorbitol or glycerol, 0.5 to 1.5 percent of calcium chloride or calcium citrate, 0.05 to 0.1 percent of potassium sorbate, 0.01 to 0.1 percent of one or more of the following ingredients: iprodione, Sportak and mancozeb, 0.005 to 0.01 percent of gibberellin and 0.025 to 0.05 percent of vitamin K. The invention can decrease the respiratory intensity, postpone the respiratory climacterics, delay the postripeness time and prolong the freshness period of mangos. Compared with the prior art, the freshness period of the mangos can be prolonged by 10 to 20 days.

An improved cleaning composition loaded on a cleaning wipe having improved biocidal release from the cleaning wipe. The improved cleaning composition includes a cationic biocide and a biocide release agent.

A metal nanoparticle colloid solution, metal-polymer nanocomposites, and methods for preparing the same are provided. The metal nanoparticle colloid solution and the metal-polymer nanocomposites can be prepared with a variety of polymeric stabilizers and have uniform particle diameter and shape. The metal nanoparticle colloid solution and the metal-polymer nanocomposites have wide applications, for example, as an antibacterial agent, a sterilizer, a conductive adhesiv, conductive ink or an electromagnetic wave shielder for an image display.

The invention relates to a convenient preparation method for culturing ecological bacteria. The product comprises a composite microbial freeze-drying strain, a special culture medium, a flora coordination and growth promotion factor and the like. After the freeze-drying microbial strains and nutrients are mixed according to the weight ratio of 1:100-1:100000, finished products are obtained by sealing and encapsulating. When in use, the product is added with water with the quantity of 20 times, the mixture is stirred evenly, the environmental temperature is controlled between 15 DEG C and 40 DEG C, and the mixture is covered by a cover, sealed at a dry position and then can be fed after being naturally activated for 2-3 days. The added water is required to be drinking water and does not contain a disinfector, a bactericide, an antibiotic and a synthetic antibacterial agent, and the temperature of the water can not exceed 45 DEG C, warm water with the temperature of 25-37 DEG C is preferred; a used container must be washed and cleaned, is provided with a cover for sealing and can be recycled by disinfection after being used. At present, most of the active bacterium products sold in the market are packaged and delivered to the market after a microbial agent and the products are fermented in a factory, which is a sale-after-growth mode; the defects of unstable effect, unreasonable performance-price ratio and the like generally exist in the active bacterium products produced by this mode. The invention adopts a growth-after-sale mode and hands the production priority of a microbial preparation to a user, and the user can prepare and culture the required ecological bacteria under a simple condition by carrying out water addition, temperature control and natural fermentation on the product. The convenient bacteria do not contain chemical medicaments and toxin and are ecological and environment-friendly.

Various devices allow for sanitization or disinfection by exhausting a dry fog biocide agent into an ambient environment. A nebulizer, for instance a vibrator that oscillates or vibrates at ultrasonic frequencies, nebulizes a biocide agent, for instance chlorine dioxide, peracetic acid, hydrogen peroxide, to create the dry fog. Such devices may withdraw the dry fog or biocide agent from the ambient environment after some period of time. Operational parameters of the devices may be tracked or monitored. Each device may implement tracking or monitoring. Additionally or alternatively, a separate tracking or monitoring system may track or monitor the operational parameters of one or more devices. Tracking or monitoring may include exception reporting, as well as other reporting.

The anti-fake pesticide-germicide is prepared with boron, saponin, pyrethroid, organophosphorus pesticide and alcohol. After the pesticide-germicide is set into various kinds of dry small mouth bottle with the lid opened for 0.25-2 hr, white snowflake-like crystal will grow around the bottle mouth, and this makes it possible for the user to identify the truth of the pesticide-germicide. Compared with pesticide-germicide of alone pyrethroid and organophosphorus pesticide, the pesticide-germicide of the present invention has greatly raised effect, lowered toxicity, lowered cost and reduced consumption.
