At this time, the yellow leaves of the eggplant are mostly the leaves in the middle of the plant. Most of the reasons are due to improper daily management such as spraying, smokers appearing in phytotoxicity or disease infestation, etc. This leads to accelerated aging of these leaves and poor adaptability to the environment. When the temperature changes are severe, yellow leaves appear.
Therefore, early measures should be taken to prevent yellow leaves when the temperature rises.
When the temperature rises, the leaves can spray the plant growth regulators that can delay leaf senescence and keep green. Such as cytokinin 1500 times or alizarin lactone 1500 times or love more than 6000 times liquid.
Keep the temperature inside the booth not too high. Due to good weather, when the temperature in the shed can reach 30°C or more, and the adaptability of the blade to high temperature is poor, the shed temperature should be kept at about 28°C, and not too high, so as to avoid accelerating the yellowing and falling leaves.
Because eggplant is more sensitive to drugs, when spraying or smoking, it should be taken to reduce the amount or shorten the time of smoking, so as not to produce phytotoxicity.
As this part of the leaves are prematurely decayed, their adaptability and disease resistance will be deteriorated and they will be susceptible to diseases. Therefore, routine management should spray chlorothalonil 600 times solution or ibuprofen 500 times solution against leaf disease. Pay attention to avoid spraying agents containing mancozeb, so as not to aggravate eggplant yellow leaves.
Amalgam Lamps
Low pressure amalgam lamps
Our companies provide high-quality spot amalgam and pellet amalgam lamps in standard and custom configurations. Our low pressure pellet amalgam lamps function with equal efficiency in both horizontal and vertical operations.
Amalgam lamps yield up to three times the UVC output over standard lamps of the same length. We have applied our proprietary process to the amalgam line. Our special proprietary coating eliminates the common problem of accelerated depreciation so often associated with higher intensity lamps. Our lamps have an operating life of up to 16,000 hours, maintaining an end-of-life UVC output of 85%.
Amalgam lamps offer the best performance over a broad air and water temperature range (4 – 40°C) with consistent UVC output; custom designs for higher temperature applications are available. They are available in both ozone generating and ozone-free lamp types.
System designers have the ability to further decrease the number of lamps used in their treatment systems.
