Tea in our country has a vast area and a wide variety of products. It is an important daily consumer product for the people of our country, and at the same time it is the main agricultural product for export. At present, the tea market, especially tea exports, has a high quality and safety requirement for tea.
At present, "non-pollution production" has been implemented in China's tea production; vigorously popularizing and popularizing comprehensive treatment technologies for pests and diseases has greatly reduced the amount of chemical pesticides used in tea production; and it is forbidden to use some stability and systemic absorption in tea production. Pesticides (such as 666, etc.); Promote the use of pesticides, plant pesticides, and microbial pesticides that are low in toxicity, high in efficiency, low in residue, low in water solubility, and easy to degrade; and establish a safety interval system for pesticides in tea production. Biological pesticides, including microbial pesticides and botanical pesticides, do not cause pollution to tea and the environment, have low toxicity to humans and livestock, and do not constitute residual drugs. Therefore, they are suitable pesticides for producing green food tea. In the current production of A-grade green food tea, especially organic tea and AA grade green food tea, the use of the following biological pesticides is worth promoting.
Rotenone. Also known as gutlet, it is a plant-derived insecticide with a long history of application. Easy to decompose in the air, low residue, friendly to the environment. It has contact and stomach poisoning effects on pests. Its broad insecticidal spectrum, short duration, usually 5 to 6 days, only 2 to 3 days in summer sunlight. It can be used for the production of Class A green tea, control tea aphids, tea caterpillars, tea silkworms, leaf roller moths, codling moths, moths, small green leafhoppers, blackthorn mealybugs, tea alum, with 2.5% rotenone EC150~250mL per 667m2, Diluted with water to 300 to 500 times liquid spray. This pesticide cannot be mixed with alkaline pesticides. Rotenone is highly toxic to fish and should be used to prevent contamination of fish ponds.
Matrine. Also known as oxymatrine, it is an alkaloid preparation made from the roots of Chinese herbal Sophora flavescens and fruit extracted with an organic solvent such as ethanol. Easy to degrade in the environment, almost no residue. Prevention of black tea moth, tea caterpillar, in the 1st, 2nd instar larvae, or egg hatching peak, every 667m2 with 0.2% matrine AS50 ~ 75mL, add water 50 ~ 75L, diluted into 1000 ~ 1500 times liquid spray. It can be used in organic tea gardens to control tea worms. Before the 3rd instar larvae, EC was killed with 3.2% insects per 667m2.
A Heating Pad is a pad used for warming of parts of the body in order to manage pain. Localized application of heat causes the blood vessels in that area to dilate, enhancing perfusion to the targeted tissue.
Heating pad is used for soothing painful joints & sore muscles & promote blood circulation in the form of heat therapy. Normally it is regulated by a controller with 3-4 heat settings.
