Question

Grey speck disease in oats takes place by the deficiency of
a) Zinc
b) Copper
c) Potassium
d) Manganese

Answer 1

A plant disease is characterized as whatever keeps a plant from performing to its normal functions. This definition is expansive and incorporates abiotic and biotic plant illnesses. Fungi, oomycetes, bacteria, viruses, viroids, viral organisms, protozoa, nematodes, and parasite plants are organisms that cause infectious diseases.

Complete answer:
Grey speck disease is a non-pathogenic inadequacy disease. It occurs as a result of a manganese deficiency. Due to severe scarcity, the yield may completely vanish. It causes greyish-earthy coloured extended spots and streaks, void panicles, and interveinal chlorosis on the stem and leaves. The side effects that occur only on leaves are unpredictable, greyish earthy coloured sores that mix and cause the leaf to breakdown. This is referred to as a grey speck symptom.
Grey speck disease, a non-parasitic post-reap confusion of white cabbage, is depicted. The rate of this deviation showed critical contrasts between years and between areas. These distinctions' causal variables are unknown.
Unmistakable contrasts in safety were evaluated between strains of 'Langedijk Storage White'. A polygenic framework with added substance and non-added substance parts protects against dark bit illness. Heritability ratings were low. The degree of obstruction could be greatly increased by family determination for two ages. Complete removal of the qualities causing dark bit sickness is most likely only possible through line determination.

Note:
A good fungicide shower programme, as well as providing adequate ventilation to the plants by pruning and then applying a fungicide to the pruning wounds, can help reduce misfortunes from this illness.
