fungus disease and bacteria disease (Akpoguma, 2003).

Insecticides
Insecticides
These
are agro-chemical (insecticides) used in controlling insect pests. According to
Cletus (2005) there are two categories of insecticides namely immediate knock
down and residual. The immediate knock down insecticides that act immediately
when applied they act by immediate contact.

Some
examples of insecticides vetox 85 applied to vegetable crop pest, (Nuvacron,
cralex for killing mosquito). Vector 85 1.5kg/ha-malathion, gaminalia 20 (one
cup full/ha), yam shoot beetle (glanderous livid) dimecron 1.5kg of chancil in
9 litres of water/ha

2) Herbicide
These
are agro-chemical herbicides used in killing weed in order to clear them off
the farm.
are agro-chemical herbicides used in killing weed in order to clear them off
the farm.
Some
herbicides resist chemical decomposition and leaching while other does not. In
many cases the rate and frequency of application soil type and climatic
condition determine the length of time that chemical remains in time soil.
Examples of herbicides are Gramaxone, triezene agro/chemical/absorption is by
roots foliage, cymezine absorption is by roots only, methylbromide, diquat and paraquat

3) Fungicides
These
are agro-chemical (fungicides) use in killing to slow down the growth of the
target disease. They have residual consequences on the crops. Examples of
fungicides include Benlate (furedam milk control), Dithene 45 (3kg/ha), Difilatan
manels and Zinels, all in powder form is use to control antharaimose (fungus
disease) in Okro plant spray every 7 days after 2 weeks of planting.

4) Bactericide
These
are agro-chemical for controlling bacterial disease in crops. They also love
residual consequences on crops. Example, (Md. M’45 use in controlling cassava
mosaic disease or cassava Bacterial Blight (CBB) in cassava
