<farmer’s name>, emidacloplete is for controlling large sucking pests, and will not be e!ective for [green and black] sucking pests. Instead of that you can use phosphamidon or metasystock. This would be more e!ective. DDVP that you sprayed will also do.
Salute to farmer friends, <name> from Kolava. For an earlier question about green and black sucking pests, which pesticide should be sprayed? We received answer from elsewhere that emidacloplete with carbon sulphide can kill green and black sucking pests. Also, when SAT with DDVP is applied the green and black sucking pests die.

Experience Sharing
Hello. <name> speaking from Beyok village, Vav taluka, Banaskantha district. Mobile number <number>. I want to inform all farmer friends that for summer vegetable crops, if you find insects, then you should create supports for birds to sit. They can control heliothis. If you use a light at night, then other insects can also be controlled. This can be done in lucerne fodder. We have done this experiment in winter mustard crop.

Salute to farmers. I want to inform farmer friends that questions asked should be useful to all farmers. Film songs or jokes in between should not be posted. If the question asked is good, all farmer friends will also enjoy listening.
Moderation
Hello. Earlier, <farmer name> had [made recordings] like this. Are you making fun of DSC by asking such questions? Or are you asking for information useful to farming? You have not been given this number for such fun or for timepass...

Hello. <name> speaking from Beyok village. Three farmer friends here have asked this question. They had [planted] psyllium. It was time of harvesting cumin. Due to unseasonal rains and cyclone, there is 60-80% loss in cumin. For this if it has to be presented to government, then on preliminary basis how can the presentation be done? Request to give answer.

I’m always the first one [in the village] to implement new methods and technology in agriculture. I have everything in terms of technology here. Everybody comes to see things at my place. Even Avaaj Otalo — I am the first one to get it in this place. So many experts and scientists are friends with me and I tell them about AO. When they are here they ask to see it and I show them how AO works. They are impressed by how much modern technology and knowledge I have. It is a matter of pride for my family.

Gaining status

Why would I use such a system [like AO]? Everybody’s answer has the same value no matter how correct or incorrect it is. I am already respected in my community as someone knowledgeable in agriculture and my answers on [AO] will be treated just like anyone else’s o! the street. How does AO benefit people like me? In fact it does not even recognize the knowledge and wisdom I have gathered over the years.
Challenging social status?

People preferred answers from authorities over peers
Who do you prefer receiving answers from?65% DSC only 35% DSC and farmers0% Farmers only(n = 36)
[Only] when these other farmer’s questions will be answered by an expert, then I will get to learn from [answers]. Farmers don’t know everything, right? What most of the farmers talk about is common knowledge to us. So I am interested in listening to what the experts say about the questions on AO.

A Farmer Responds
So much gratitude to you, and also if I want to sow something now, I’ve got a little extra water, so what should I sow that would be best suited for me?
In the seven years I have been farming this is the first and only time that I have received satisfactory information.
I give praise to Avaaj Otalo. I will be forever in your debt for the knowledgeable response you gave to my question ... Farmers will learn so much if an ordinary person is able to ask a question and you send me a message while I am sitting in my house.
