  • the present invention relates to a method for controlling magnesium deficiency.
  • Magnesium in the plant body is an essential element for the growth of the plant body because it is a constituent element of chlorophyll.
  • magnesium is easy to move in the plant body, and when the amount (total amount) of magnesium in the plant body is deficient, it redistributes from old leaves (lower leaves) to new leaves (upper leaves). For this reason, magnesium tends to be deficient in lower leaves, and chlorosis (yellowing or tanning between veins) occurs.
  • Such a symptom appears as a main symptom of magnesium deficiency, and when magnesium deficiency progresses, necrosis (necrotic spot) of chloroplasts occurs, and eventually the leaf blades die.
  • magnesium deficiency tends to occur in the leaves in the vicinity of the fruits. Since the occurrence of magnesium deficiency causes the quality of the fruit, which is the harvest, to be impaired, it is important in agricultural management to take control measures against magnesium deficiency. As a control measure against magnesium deficiency, it is effective to apply magnesium-containing fertilizers, chemicals, and soil conditioners (hereinafter referred to as magnesium-containing agents) to the leaves of plants or apply them to the soil.
