* Site of injuries by insects may predicspose crops to disease attack.

*They Increase cost of production during the course of controlling them.

*The profits of farmers are automatically reduced.

*They can also cause total death of crop plant

*They render vegetables and fruits unattractive and unmarketable.

* They generally reduce the yield of crops.

*Some are carriers or vectors of diseases

*They reduce the quality of produce wither in the store or in the field

prevention And Control Of pests

Crop pests cans be prevented or controlled through the following methods: chemical control , biological control, cultural control and physical control.

*Physical control involves the physical removal of pest by handpicking of insect and larvae, setting traps to catch rodents, shooting rodents with gun and fencing round the farm yard with wire.

* Cultural control involves the use of farm practice to prevent or control pests especially on the field, example of cultural control includes : Bush fallowing , crop rotation , regular weeding, proper timing of planting  bush burning then proper time for harvesting.

* Biological control involves the introduction of the natural enemies of pests to  control or keep the pest population under control. Such enemies eat up or feed on the pest thereby reducing the population of the pest .

* Chemical control is mostly use by farmers which involves the use of chemicals called pesticides to control pest of crop plant.

1 . Cultural Control :

Cultural Control involves the use of crop rotation, resistant varieties ,tillage practices, regular weeding , fallowing, timely planting, pruning uprotting, burning of infected crops to control or prevent disease s.

2 . Chemical control : 

Chemical Control involves the use of chemicals such as fungicides, nematicides–, insecticides to dust or spray on plant and plant materials in order to prevent or control plant disease.

3 . Biological control :

Biological control involves the use of natural enemies of the disease to reduce or totally eliminate the disease.

Summary Of General Control Measures Of Diseases Of Crops

*  Regular weeding of the farm to prevent disease pathogens from being  haboard  by weeds

* Practise crop rotation.

*Removal and burning of infected crops

*Planting disease resistant varieties of crops

*Using healthy seeds or stems for propagation

*Practice seed dressing with plant protection chemicals such as Fernasan D before planting

* Spraying plant protection chemicals such as fungicides and nematicides–

* Early planting to avoid the period of disease occurrence.

*Spraying insecticides to control the insects vectors .

*Destruction of crop residue after harvesting to prevent the build – up of disease pathogens or practice goodfarm sanitation or hygiene.

*Sterilisation of soil to control soil – borne diseases

*Avoid close  planting to reduce the rate of spread of diseases.
