The plant needs its leaves

If a plant has many big leaves, the harvest will be good.
If a plant has few, small leaves, the harvest will be less good.
Plants sown at the best density (see Booklet No. 1, page 26) will have the best leaves.
The roots will find enough food, and the leaves will change this food into organic matter, and the harvest will be good.
When plants of cotton or maize are too close together, the surplus plants are removed.

· Some insects eat leaves and buds.

Young leaves are eaten first, because they are not hard.
When the insects are born, the plants should already be strong.
The leaves, being harder, will be less attacked.
Plants sown at the right time will be strong when the insects appear.

Leaf eaten by insects

· Insects and diseases can be destroyed.

You should pull out diseased plants.
Let them dry.
Burn them.
Insects and diseases are killed by fire.
Certain seeds produce strong plants.
These strong plants resist diseases and insects better
Sow seeds which resist diseases and insects.
To kill insects or to prevent diseases, pesticides can be used.
These pesticides are poisons.
You cover the leaves with them and the insects are killed.
Often you need a sprayer, so that the pesticide covers the whole plant:

These pesticides can be dangerous to men and animals. You have to be very careful.

You must use exactly the quantity written on the containers, no more and no less.

· Animals also eat leaves.

Leaves and plants must also be protected against animals, such as goats, cows, agoutis, monkeys.

Put fences round the fields, keep a watch on cows and goats; put them in a paddock.
