It is common for crops to have phytotoxicity. When crops are being tested for pests and diseases, factors such as improper use of pesticides , poor quality of pesticides, and poor concentration of pesticides may cause crop phytotoxicity. Pay attention to pesticide information and pay attention to China's pesticide network !
We supply various fitting light (fitting
lamp), including Led Purification Fixture, LED Tube Light Fixture, LED Split T8
Tube, T5 LED Tube Light etc.
The below information will help you to know
more about fitting light.
What is used for light fitting?
Aluminum is used in light fitting design
either as casted aluminum, extrusions or sheet metal. Many alloys are commonly
used.
How many types of tube lights are there?
Fluorescent tubes (officially known as
"lamps") come in five basic types, identified as T2, T5, T5HO, T8,
and T12, and The "T" designation stands for "tubular," and
the following number refers to its diameter in 1/8-inch diameter increments. 1
A T12 bulb, for example, is 12/8 inch in diameter, or 1 1/2 inches.
T5 and T8 are the popular ones.
T5 (16mm Diameter)
T5 tubes have a diameter of 16mm. They can
be used to illuminate anything from schools to underground railways. They're an
ideal choice for illuminating large spaces because they typically last up to
20,000 hours, they also have a low mercury content, limiting environmental
impact. T5s have a high quality light output and colour rendering.
T8 (26mm Diameter)
T8 tubes have a diameter of 26mm. They can
be used in schools, garages, offices, retails stores and most other
environments. They have excellent colour rendering and can last up to 42,000
hours. Versions available now include LED Tube Lights and standard gas filled
tubes

The occurrence of crop phytotoxicity affects the growth of plants and reduces production. Therefore, it should be timely rescue crop injury; pesticide Xiaobian below China has come up with "methods of crop injury rescue."
The following methods are summarized in the “ Methods for Remedying Crop Injury â€.
1. Irrigation and disinfection to reduce the degree of phytotoxicity.
For some herbicides and some toxic substances caused by poisonous soil, water can be drained or serially irrigated to reduce the degree of phytotoxicity. If plant dwarfism caused by herbicide is used, watering and disinfection should be carried out immediately in the initial stage. After that, interstitial irrigation and quick-acting fertilizer can greatly reduce the degree of phytotoxicity.
2, spray water to wash drugs, reduce pesticide concentration and reduce crop phytotoxicity.
Spraying pesticides caused phytotoxicity to plants and leaves, and found early, the damage was light, and the pesticide did not penetrate into the plant body. The damaged plants could be sprayed quickly with water or 0.5% lime water, and sprayed 3 to 4 times repeatedly to wash away the parts. The decomposition of the drug solution and the accelerated drug may be combined with the fertilization of the soil to restore the growth of the crop.
3. Remove the parts of the phytotoxicity and prevent the phytotoxicity from continuing to expand.
The use of insecticides with strong systemic absorption is often applied to the fruit trees by perfusion, injection, dressing, etc. If the concentration is too high, the damage to the damaged branches should be quickly removed, leaving no The branch of the medicine is to prevent the medicine from continuing to conduct and penetrate downward, and to quickly fill the water to prevent the medicinal damage from continuing to expand.
4, serious phytotoxicity, ploughing and replanting.
The phytotoxicity is serious, and most of the plants are dead. When the field is first exposed to the sun, then the medicine is washed, and then the ploughing is turned over, so that the residual pesticide in the soil has no effect, the crop is replanted. If local phytotoxicity occurs, first rinse with water, local tillage and replanting, and after emergence or planting, make quick-acting fertilizer, so that the later crops catch up with the former crop and reach balanced growth.
