Ethylenediamine Two Adjacent Hydroxyphenyl Big Iron Sodium Acetate,
EDDHA Fe 6%
Iron is one of the micronutrient elements necessary for the normal
growth of plants. Although its content in plants is not high, it
plays a very important role in the growth and development of
plants. Iron is not only involved in the physiological processes of
plant chlorophyll synthesis, respiration and redox reaction, but
also an important cofactor for many functional proteins.
Symptoms of iron deficiency in plants
1. Iron deficiency in grapes: In the initial stage, new leaves are
chlorosis, only the leaf surface remains green. In severe cases,
irregular brown necrosis occurs on the leaf margins and tip, the
branches stop growing, the tendrils are larger, and the leaves look
like Burning; low fruit setting rate, sometimes all the flower buds
fall off, and the fruit particles are small.
2. Iron deficiency in citrus: the veins of the leaves are green
reticulated, the veins are yellow-green, and the branches are thin
and weak. In severe cases, both the young and old leaves become
white, the middle veins are evergreen, and the leaves are easy to
fall off.
3. Iron deficiency in kiwi: the mesophyll turns yellow, and the
veins remain green, causing the leaf surface to show green
reticulated yellowing. When iron deficiency is severe, the top of
the new shoots will die; the fruit will turn yellow, and the fruit
will be light and tasteless.
