Cucumber deficiency symptoms and prevention

The lack of copper between the joints became shorter, the whole plant was clustered, the young leaves became smaller, the old veins were chlorotic, and the later leaves were thick green to brown, with necrosis and yellow leaves. The loss of green is from old leaves to young leaves. Control methods Apply 1 to 2 kg of copper sulphate per acre as a base fertilizer; apply 0.3% of copper sulphate twice as foliar.

Deficient molybdenum often occurs heavier in sandy soils, acidic soils, and continuous severe soils. The early symptoms of molybdenum deficiency were similar to those of nitrogen deficiency, with slight yellowing between veins, and uneven and uneven foliage at the late stage, with dry and dead spots, curled leaves or withered leaves, and new leaves distorted. Control methods apply more organic fertilizer, lime and soil acidity are applied on acidic soil. Jishi molybdenum fertilizer can be sprayed with 0.02% to 0.05% ammonium molybdate aqueous solution in emergency.
