Plant growth regulators (PGRs) are a type of **pesticide** used to control and influence plant growth and development. These substances can be either synthetic compounds or naturally derived plant hormones. To achieve optimal results, it's essential to understand both their proper usage and key precautions. Here’s a detailed guide on how to use them effectively:
First, the main points to consider when using plant growth regulators:
1. Use the correct dosage. PGRs should not be overused, as they function similarly to natural plant hormones. Typically, only a few grams or milliliters per acre are needed. Some farmers mistakenly believe that more is better, leading to excessive application. This can cause adverse effects such as stunted growth, leaf deformation, wilting, or even plant death.
2. Avoid mixing without caution. Many growers mix PGRs with fertilizers, pesticides, or fungicides to save time. However, compatibility must be checked before mixing. For example, ethephon is acidic and should not be mixed with alkaline substances. Similarly, amine esters may break down in alkaline conditions, so they should not be combined with alkaline products. Improper mixing can lead to phytotoxicity and reduce effectiveness.
3. Follow the correct application method. It’s important to read the instructions carefully before use. Some PGRs cannot be directly diluted in water and must be prepared as a stock solution first. Failure to do so can result in poor mixing and reduced efficacy. Always dilute according to the manufacturer’s guidelines.
4. PGRs are not a substitute for fertilizers. According to the **Pesticide Network**, PGRs are not plant nutrients. They regulate growth but cannot replace fertilization. Applying too much PGR in poor growing conditions can be harmful. Before using PGRs, ensure proper watering and fertilization to support healthy plant development.
Second, key considerations when using plant growth regulators:
1. Improve fertilizer and water management.
- Apply balanced fertilizers, combining organic and chemical sources.
- Ensure adequate base fertilizer and appropriate top-dressing.
- Focus on nitrogen, phosphorus, potassium, and micronutrients. Avoid over-fertilizing during fruiting stages.
2. Manage irrigation properly.
- Water regularly during critical periods like fruit setting.
- Avoid watering during midday heat; instead, water early in the morning or late in the evening.
3. Enhance tree management.
- Thin flowers and fruits based on tree capacity, removing deformed or overcrowded ones.
- Control summer shoot growth through pruning or water restriction to promote flowering and fruiting.
- Prune strategically after harvest or thinning to improve light exposure and air circulation.
4. Strengthen pest and disease control.
- Apply treatments at the right time, following the life cycle of pests and diseases.
- Use low-toxicity, high-efficiency pesticides and follow label instructions precisely.
- Avoid spraying during flowering or rainy weather, especially for sensitive crops.
Tip from the **China Pesticide Network**: Using PGRs and other agrochemicals correctly and responsibly not only helps reduce costs but also improves crop quality and yield. Always follow safety protocols and stay informed about best practices in pesticide use.
Super Abrasives
Superabrasives come in the form of grinding
wheels and are used when the material being processed is either too hard or too
delicate for regular abrasives.
Industrial diamonds are one of the most
common materials used to create the grinding material. Contrary to popular
belief, diamonds are not as rare as marketing campaigns will tell you.
After diamonds,cubic boron nitride is
the second more durable material for cutting. This is followed by
polycrystalline.
The most obvious advantage is that these
Grinding Wheels are extremely hard and durable. This allows them to give better
performance and greater longevity over regular abrasives.
When your wheel lasts longer you will see
reduced costs for fixtures and tooling. This opens up your budget up to
investing in more machines.
You will notice that the wear and cuts on
your materials will be even. Because the abrasiveness of the wheel is so
strong, it doesn`t develop uneven worn away spots as quickly as regular
abrasive wheels.
So the output from your production will be
consistent. So your manufacturing efforts will produce reliable and consistent
results.
It can be tough to justify the upfront
increased costs of superabrasive wheels. But the durability and quality of
their production output make them well worth it.
But you`ll quickly realize that your
productivity has increased by using superabrasives. You will have
more parts processed per wheel and fewer wheel changes.
Kemei produces both conventional grinding
wheel and super abrasive grinding wheels, such as white aluminum grinding wheel,
pink wheel ,green silicon wheel, diamond grinding wheel and CBN grinding
wheels.
