You possibly can be taught extra about powdery mildew in our information.
7. Root-Knot Nematodes
Root-knot nematodes (Meloidogyne spp.) may also have an effect on celosia.
These microscopic roundworms infest the roots of celosia, feeding and reproducing inside the root tissues. This results in the formation of attribute galls or knots on the roots.
The presence of root-knot nematodes can result in stunted development, yellowing of leaves, and an total decline in well being.
Celosia crops can exhibit decreased vigor and decreased flower manufacturing.
Root-knot nematodes can persist within the backyard for prolonged durations and so they could also be launched to the backyard by contaminated plant materials, contaminated soil, or water sources.
Overcrowded and poorly draining rising circumstances assist them to multiply and unfold.
8. Rot and Damping Off

Celosia crops began from seed may succumb to damping off, one other situation attributable to Pythium and Rhizoctonia, in addition to Fusarium pathogens.
Probably the most widespread issues when ranging from seed, a seedling that emerges will look like wholesome, after which it wilts and dies for no apparent cause.
Extreme moisture, overwatering, excessive humidity, and overcrowded circumstances can all result in damping off.
9. Salt Damage
Excessive concentrations of soluble salts may cause harm to celosia crops. Soluble salts check with the dissolved minerals which are current within the soil, primarily sodium, chloride, and different minerals.
When the focus of those salts turns into too excessive, it will probably create an imbalance within the water and nutrient uptake, main to numerous signs of salt harm.
Celosias are very delicate to extreme salt accumulation within the roots, and this may negatively impression their development and total well being. Some widespread signs embody leaf burn, stunted development, wilting, and decreased flowering.
The leaf edges and ideas could flip brown or yellow, and in extreme circumstances, they could develop into necrotic and dry out. The leaf tissue could seem scorched or crispy.
