NEW BIOLOGICAL CONTROL OF THE COFFEE BORER
Here is the first step: the top grade rice is being rigorously selected--discolored, broken grains taken out .
A deadly enemy of coffee plants across the world is the coffee borer. The coffee borer, Hypothenemus hampei, is a small beetle that, according to Wikipedia, affects the economy of over 20 million families who depend on the coffee harvest. If unchecked, it can destroy an entire harvest in one area. The female insect bores into the ripening coffee cherry and deposits her eggs. As the larvae become pupae and mature and grow, they eat the soft cherry, either destroying it completely or making it unsellable because of defects.
Strict control, in the form of visual inspection and careful removal of all infected beans on the ground or on the trees, before and also after the harvest, is the most common way farmers control the borer. As the female can fly short distances, it spreads easily. Chemical insecticides are often toxic, expensive and not very effective.
However, it has been found that the fungus, Beauveria bassiana, is a natural enemy of the borer. It destroys the coffee borer. Beauveria bassiana is a fungus that grows naturally in soils and can be cultivated and sprayed on the coffee plants.
Nueva Granada has been growing Beauveriana bassiana in our laboratory for over a year now, so as to have enough to spray against the coffee borer. Anacafé, the coffee growers association, gives the Beauveriana bassiana spores to farms at no charge.
First the medium, top grade rice, is carefully selected, washed and disinfected. It is then precooked for 20 minutes. The rice is cooled and inoculated with the Beauveria bassiana and put in sterile bottles. It rests 20 days in the laboratory and then it is ready to be taken into the field.
In the field the rice is washed with a solution of oil and water and the resulting suspension is sprayed on the coffee. The suspension from seven pounds is used per hectar.
Here are the Nueva Granada labs to incubate and grow Beauveria bassiana. The bottles rest without movement for 20 days while the fungus grows.-
These three students from the Instituto Telesecundaria de Finca Nueva Granada won prizes in a six school reading competition sponsored by Anacafe held on October 19th.
Third Year student Claudio Manuel won
Second Year student Karla Paola won
First Year student Helen Beatriz won
The Institute is very proud of them. Again.

A Wonderful Visit
We just had four young Japanese coffee people make the long trip to Nueva Granada. They were full of enthusiasm! And so were our students!
We had to reinforce the roof over the wet mill so it could bear the weight of the solar panels. But they are now installed and working. We produce about 50 kilowats which helps us reduce our electricity bill. And the neighbor has already asked if we can put him in touch with the people who did ours. So green is contagious and good!!
Our athletes, has won several competitions so far
