Necrosis and choloris symptoms on leaves appear a lot. This usually happens because the growth is somehow stunted causing messy leaf appearances. Being able to identify and take care of necrosis and choloris is very important.
Chlorosis is when certain tissues, especially on leaves, are damaged and indicated by the failure to form chlorophyll on leaves so leaves aren’t green, but yellow or even white-ish pale.
Chlorosis can be prevented by using fertilizer with zinc in it. As known, zinc is an essential micro nutrient for plants. Zinc is also the activator of several types of enzymes, chlorophyll forming, and helping in photosynthesis.
On the other hand, necrosis is a symptom of certain tissues’ death on plants. On stems, it will appear as dark brown lines that aren’t usually there on healthy plants. On leaves, it will appear as specks on leaf surface. Those specks may also appear on fruits. Death on primary and secondary growth points may also occur on some plants.
If you don’t act quickly and anticipate necrosis and chlorosis, your crop will be more vulnerable to pests and diseases thus hindering their growth and development process.
Here are several things you can do to prevent and cope with necrosis and chlorosis:
- Do your watering properly using clean water so the minerals in it can be absorbed and used effectively by plants. Polluted water will affect your plants’ quality and harvest that can be dangerous for humans as consumers. You must pay attention on different dosages of watering for different stages of plants.
- Scheduled fertilization is also important. Both organic and non-organic fertilizers contain important macro and micro nutrients for your plants’ growth and development. To prevent necrosis and chlorosis especially, make sure to use fertilizers that are rich in zinc, manganese, nitrogen, magnesium, potassium, and calcium. Those nutrients are important to disintegrate enzymes in leaves and for cell metabolism in several tissues and organs, especially leaves and stems.
- Keep your soil’s humidity stabile. This can be done by using plastic mulch on your seedbeds. Using plastic mulch on your seedbeds also helps in keeping soil’s acidity (pH) stabile and efficient.
- Pay attention to how much light your plants are getting. Light is important for plants because it is a core ingredient in photosynthesis. Light is also a reflector for chlorophyll pigments on leaves to respond to changes of chemical compounds during photosynthesis. Light also helps leaves to stay healthy.
I hope this information will help fellow farmers and gardeners in taking care of your crops.
