In the absence of molybdenum in soybeans, not only the leaves are thick and wrinkled, but also the leaves are pale, and many small taupe spots appear. The edges of the leaves are curled up and cup-shaped, and the number of nodules on the roots is small, root nodules are also small, and development is poor. The characteristics of molybdenum deficiency are different from those of boron deficiency. Although molybdenum deficiency is also the first symptom of new tissue through the old tissue, the growth point is not easy to necrosis.
Prevention:
(1) Apply molybdenum fertilizer. The commonly used molybdenum fertilizer is ammonium molybdate. The seed dressing and spraying may be adopted. Generally, 2 g of ammonium molybdate is used for seed dressing per kilogram of seed, and the concentration of sprayed ammonium molybdate solution is 0.005%-0.01%.
(2) Mixing molybdenum and phosphorus. Since phosphorus can promote the absorption of molybdenum by crops, molybdenum fertilizer can be mixed with phosphate fertilizer. This method is convenient and effective.
(3) Apply lime. The lack of molybdenum occurs in acidic soils. The use of lime in acid soils can reduce the acidity of the soil and increase the effectiveness of molybdenum.
The Fluorine-Containing Benzoic Acid series is very common form of the fluorochemical compounds, it has many product types and derivatives. Most of products are in white crystalline powder, some of products are Colorless monoclinic prismatic crystals. It was widely used as fungicide intermediates, also used in the etching process. The Fluorine-Containing Benzoic Acid series are mostly in high value-added , less polluting products. We are trying our best to make our production dock with market to give accurate and effective services for the market .
