When pesticides are used to control vegetable pests and diseases, the dosage is small, the control effect is good, and the toxicity to humans, animals and various beneficial organisms is small or non-toxic, requiring easy decomposition in the external environment, and not causing high efficiency and low toxicity to the environment and agricultural products. Low residual pesticides. Specifically: the dosage per acre must be determined from the actual situation. Through experiments, the economically effective concentration and dosage should be determined. It should not be too high or too low. Generally, the insecticidal effect is over 90%, and the disease prevention effect is more than 80%. High-efficiency pesticides; use (LD50) low-toxic pesticides with a lethal median value of more than 500 ml/kg body weight; the harvested commercial vegetables should pay attention to the safety interval of pesticides, so that the pesticide residue must be lower than the national standard.
1. Biological pesticides
Bio-sourced pesticides refer to the direct use of biologically active substances produced by biological organisms or biological metabolic processes or substances extracted from organisms as pesticides for controlling diseases, insects, grasses and other harmful organisms. Specifically, it can be divided into plant-derived pesticides, animal-derived pesticides and microbial-sourced pesticides. Such as: BT, pyrethrin, nicotine allicin, sex pheromone, Jinggangmycin, Nongkang 120, Liuyangmycin, streptomycin, polyoxymycin, avermectin, brassinolide, except Alizarin, alkaloids, etc.
Second, mineral source pesticides (inorganic pesticides)
The active ingredient is a generic term for inorganic compounds derived from minerals. There are mainly sulfur preparations, copper preparations, and phosphides. Such as copper sulfate, Bordeaux mixture, stone sulfur mixture, zinc phosphide and the like. Arsenic preparations and fluorides with high toxicity and high residual content are not included in the recommended range.
Third, organic synthetic pesticides
It is limited to organic whole pesticides with low toxicity, low residue and safe use. It is recommended to use safe pyrethroids, some medium and low toxicity organophosphorus, organic sulfur and other insecticides , fungicides and some low-toxic diphenyl ether herbicides after many years of application. Such as: cypermethrin, deltamethrin, dimethoate, dichlorvos, phoxim, carbendazim, chlorothalonil, metalaxyl, triadimefon, chlorpyrifos, methotrexate, anti-coccin, grass and spirit, thin Kill, grass, ger, dur and so on. High-residue organochlorine pesticides, secondary poisoning of fluoroacetamide, and metabolites such as ethylene thiourea with "triad" are not recommended.
The flush plate is an essential component of a concealed installation system that remains visible to the user. Fabia, a brand that pays great attention to design elements and reliable functionality, offers a range of flush plates with different designs, materials, colors, and finishes. These flush plates not only serve as switches for flushing but also provide access to the hidden water tank for maintenance purposes.
Fabia manufactures flush plates primarily using three materials: ABS plastic, stainless steel, and glass. Each material offers unique aesthetic and functional characteristics to complement the overall bathroom design. The choice of material depends on the customer's preference and the desired visual appeal.
In terms of functionality, flush plates can be categorized into three types: mechanical (manual pressing), pneumatic, and sensor-based. Mechanical flush plates require manual pressing to initiate the flushing process, providing a traditional and tactile experience. Pneumatic flush plates utilize air pressure to trigger the flushing mechanism, offering a touchless operation. Sensor flush plates use advanced technology to detect the user's presence and automatically activate the flushing system, providing a convenient and hygienic solution.
The majority of flush plates available on the market are dual flush panels, which allow users to choose between two flush volumes based on water consumption. Typically, a short flush consumes around 3 liters of water, while a long flush utilizes 4.5 to 6 liters. The dual flush button design is the most common type of flush plate, ensuring both economic and environmental savings by promoting water conservation.
In a word, Fabia's flush plates are designed to combine functional efficiency with aesthetic appeal. By offering a variety of materials, designs, and functional options, Fabia enables customers to select the flush plate that best suits their needs and preferences while promoting water-saving practices and enhancing the overall bathroom experience.
