PROTECTION OF NURSERY AGAINST PESTS AND FUNGI:
A constant watch should be kept on the nursery for fungal or insect attacks. Moreover, consider other problems ie grazing, wind, and burrowing animals.
Protection against burrowing animals:
A wire mesh is buried in the soil or passed under the ground in such a way that half of it should be in the air. The depth under the soil is 2ft.
Protection against birds:
Thorny bushes are placed over seedbeds. The frame of wire gauze is also used which is usually placed on the seed beds.
Protection against grazing animals:
Grazing trenches are dug up or wire fencing is done.
Protection against rainfall and hail:
A wire cover should be provided over seedbed.
Protection against the wind:
Hedges are raised which are normally tall. In winter they are cut down for sunlight.
Protection against insects and diseases:
Spray and fungicides or herbicides should be made if the crop is attacked by some fungus, etc.
Protection against frost:
Polythene sheet covers are used which also control the temperature and helps in growth.
