Article: Cotton farmers in some Indian villages are flooding to buy Coca-Cola and Pepsi, believing that the sugar in the fizzy drinks kills pests . Farmers say scientists advised them to mix pesticides with a sugary syrup to control pests, and they found the mixture cheaper and more effective than pure chemicals---- although soft drink makers and scientists dismissed the claims. N. Hamunayya, who has become famous in his village in the southeastern state of Andhra Pradesh, said his crop survived an attack of pests which had resisted other solutions. "We found that all the colas had the same effect on pests. The pests became numb and fell to ground," he said.He said the drinks had all the elements they needed: they were cheaper, sticky, fizzy, and attracted ants, which swallowed the larvae( )of the pests. But Thirupathi Reddy, assistant director of the Regional Agri Research station, Guntur, says tests had denied such claims. " We conducted some field trials on cotton crop at our research station. There were no increases of productivity or deaths of pests," he says. Statements from Pepsi and Coca-Cola said there was " no scientific basis" for this practice. But their sellers are enjoying booming sales. Mantan Wali, who sells soft drinks in 17 villages in the region, said sales increased , thanks to the farmers. " For the 10 days between August and September I had booming business. Instead of just 30 cases ( each containing a dozen one-litre bottles) of cola I started selling almost 200 cases, " he said.

I told him that I couldn't do it. He asked, "Why not?" I paused, and then I said, "Because I'm educable mentally retarded ." He came from behind his desk and looked at me. "Don't ever say that again. Someone's opinion of you does not have to become your reality," he said. It was a very special moment for me. Doctors said that I was educable mentally retarded in the fifth grade, and I was put back into the fourth grade. When I was in the eighth grade, I failed again. But Mr Washington changed my life. This person always gave students the feeling that he had high expectations of them, and then all of the students did their best to live up to what those expectations were. He often said, "You have greatness within you." One day, I caught up with him in the parking place and said, "Mr Washington, is there greatness within me, sir?" He said, "Yes, Mr Brown." "But what about the fact that I failed in English, math and history? What about that, sir? I'm slower than most kids." "It doesn't matter. It just means that you have to work harder.

"Mr Washington?" "What do you want now?" "Uh, I'm the one, sir. One day you're going to hear my name. I'm the one, sir." School was a real struggle for me. Mr Washington put many demands on me. He made me believe that I could do it. At the end of that year, I was on the honor roll for the first time in my life. Years later, I produced five programs on public television. When one of my programs was shown on the educational television channel, I had some friends call him. I was sitting by the phone waiting when he called me. He said, "May I speak to Mr Brown, please?"
