The Urine Reagent Strip Rapid Test is based on a double sequential enzyme reaction. One enzyme, glucose oxidase, catalyzes the formation of glucomic acid and hydrogen peroxide from the oxidation of glucose. A second enzyme, peroxidase, catalyzes the reaction of hydrogen peroxide with potassium iodide chromogen to oxidize the chromogen to colors ranging from blue-green to greenish-brown through brown and dark brown.

First, the biological characteristics of earthworms. The larvae are head-shaped, 6 to 9 mm long, black on the head, and milky-white, with a smooth surface, a sharper front end, and a slightly flatter rear end. Adult worms are small mosquitoes that fly poorly and fear light. Often gathered in groups, soon after mating in the original land egg, causing field plots occur, serious damage. The eggs are prolific in the 3 to 4 cm below the roots of the leeks and they feed on pseudostems and bulbs. The larvae prefer to live in moist, juicy tissue. In general, wetlands and loam lands are seriously damaged.
Second, prevention and control methods. At present, it is the peak period of the occurrence and damage of the leeks in open fields. It is possible to use 20% guanidine to protect the EC, generally 1 kg per mu, and dilute the agent to 100 to 200 times. Shennongbao 500 ml or 50% phoxim 0.75 to 1 kg is poured into the field with water. For greenhouses, greenhouses, and other protective areas, it is generally necessary to conduct two prevention and control, and the first prevention and control will be carried out before the sheds are sheltered. After the winter shed, due to the increase of soil temperature, the larvae regained their awakeness. After cutting the head leeks, the larvae were plunged to prevent and control the leeches. The depth of the larvae was generally 3 to 4 cm, and then the medicine was sprayed. 55% phoxim 500 was used as a common medicament. ~600 times liquid and so on.
The test area of the Urine Reagent Strip Rapid Test is specific for glucose; no substance excreted in urine other than glucose is known to give a positive result.Approximately 100 mg/dl glucose in urine is detectable.
The Urine Reagent Strip Rapid Test is based on the protein error-of-indicator principle. At a constant pH, the development of any green color is due to the presence of protein. Colors range from yellow for a Negative reaction, to yellow-green and green to blue-green for a Positive reaction.

Aphid, the scientific name leeks, is a major underground pest in the production of leeks. It occurs in all regions of Fujian Province. It usually occurs in four generations each year. It occurs in the beginning of May, the middle of June, the beginning of August and the end of September. Adults lay eggs under the earth seams or clods around the alfalfa. After the larvae hatch, they are trapped in the bulbs and tender stems of the leeks, causing the young stems to rot and the yellow leaves of the leeks to rot and die. The death of whole leeks caused great impact on the yield and quality of leeks. Nowadays, it is the critical period for the prevention and control of cockroaches in the fall. Below, we briefly introduce the biological characteristics of cockroaches and the methods for the prevention of pollution.
