How to use pesticides for pollution-free vegetables
Our safety grating create safer working conditions across a variety of industrial environments. Some of the industries that benefit from using our products in the construction of their walkways, ladders, stairs, ramps.
Stair treads metal grating offers a number of advantages. The material provides greater strength, reliability, and flexibility, qualities that make it well-suited for use in critical structures, such as stairs, ducting, roofing, and more.
hot rolled, cold rolled, aluminum, galvanized plate,
stainless steel panel etc.
Anti-skid plate can be widely used in sewage treatment, power plant,
snow, stair step, antiskid pedal, and many other anti-skid areas.

First of all, you should choose a biological pesticide or biochemical preparation that has good effects and is not toxic or extremely toxic to humans, animals and natural enemies. For example: bt preparation has good control effect on cabbage caterpillar and diamondback moth. Such preparations are eaten into the stomach by the worms, and under alkaline conditions, the toxicity is caused to cause the insects to die. Human and animal stomach are acidic, Bt toxicity can not be exerted, and it is safe for humans and animals. Biochemical preparations refer to agricultural antibiotics, such as streptomycin and penicillin, which can be used by the human body. It is of course safe to use on vegetables.
The second is to select specific insect growth regulators, such as chlorbenzuron, Nongmute, Youle, and Taibao. The insecticidal mechanism of this kind of chemical pesticide is to inhibit the growth and development of insects, so that it can not be peeled and ageed, and its insecticidal activity. Very high, very low toxicity to humans and animals.
The third is to choose high-efficiency, low-toxic and low-residue pesticide The normal use of such pesticides will not cause poisoning accidents and is safer.
The fourth is to select a medium-toxic and low-residue pesticide with good efficacy. There are many kinds of vegetable pests and diseases, which are serious, especially some disaster-causing pests and diseases. If they are improperly controlled or not timely, they will cause devastating losses. There are few varieties of biological agents and specific functional preparations, which are highly specialized, have limited opportunities for selection, and the pesticides are less effective in quick-acting. Medium-toxic pesticides can be used in cases where low-toxic, low-residue pesticides cannot control pests and diseases. The application of such pesticides must pay attention to: first, according to the safe use of pesticides; second, to select agents with lower toxicity, it is safer to choose pesticides with LD50 over 100 or above.
Our safety grating provides a lightweight but durable surface that reduces the risk of slipping. It is suitable for use in many crane components, including the stairs, walkway, and operating platform.
The material offers durability and slip resistance-even when exposed to harsh road conditions, such as rain, snow, sleet, and dust-qualities that help ensure the safety of workers during loading and unloading operations.
Safety grating is used for many truck body components, including steps, flooring, and work platforms.
Features:
Corrosion resistance, Rust resistance.
