My mother loves plants. She has quite a wide array of plants in the modest space of my home.
Lately, she has been troubled by an increasing pest problem. An insect called Mealybug has infected trees of hibiscus, mango and guava resulting in heavy defoliation(loss of leaves). She has used many spraying insecticides to no avail(mealybug develops a waxy coating which doesn't let the poison sip in).
After quite a lot of thinking and administering the sprays myself, I decided that there must be some array of chemicals which can be administered from within the plants. The chemicals go with water at the root, the insects ingest it along with the sap and then, die. Quite obviously, the chemicals shouldn't disturb the metabolism of plants.
A single search query gave me the answer. Systemicides. One of them is called imidicholoropid. Shortly afterwards, I took my bicycle and reached the nearest agro shop. I began to describe what I wanted. Here is a snippet of the conversation with the shop attendant S.
Me: Do you have an insecticide which can be administered to the roots?
S: Huh? There is nothing such as that. Describe me your problem.
Me: <Description given>
S: Oh, you take this pesticide. Spray it all over the plants. It is enough.
Me: No, it isn't. It has already been tried.
S: Tell me again what you exactly want.
Me: Have you heard of imidicholoropid? It works by getting into plants along with the water. The insect dies after ingesting the sap.
S: (smiling mockingly) Is it even possible?
Me: Yes. It is science. You use internet? There are pages and pages on the agricultural websites.
S: Dude, I am a practical person. I am in this business for 22 years. Science has not yet developed enough. What will fancy degrees do? I know more stuff than a person at an agricultural institute. (he then went on to describe his success at various farms and how he taught various degree holders 'things')
I left the shop feeling weird. A man who runs his living by selling things made possible by science(fertilizers, pesticides and genetically modified seeds) believes that science is a joke. What do you think is the condition at the level of farmers?
I don't know why science has such an outlook among the general public. Or why people tend to believe in religion or fantasies more often and far strongly than science. Forget those who never went to school - I have seen many educated people falling into the trap too. It is deeply troublesome that this question has not been sufficiently asked - what is the essential thing missing from science education?
I don't know the answers yet. But, I do know one thing as far as the human society is concerned.
Bullshit baffles brains.
