At last we found beetles.
On May 18 one of my worker brought one beetle to my house.And it was burmistry beetle.He said that a good number of such beetles were there in his farm yard.Last year he had seen hund
reds of beetles in one plant,he said.There after he collected as much as beetles he can.
On June 19 Dr.A.R.V.Kumar came and took samples for grub activity.That night we went to that workers house to collect beetles.We found around 20 beetles in one cashew plant.But the surprise is that beetles preferred one single cashew plant.It could not be seen in other cashew plants.The next day again that worker ,Koragappa Gowda,brought few more beetles.Dr.Prakash told that most of it was female one.
One good thing happened this time is that we learnt to differentiate male from female beetles.I think this will be considered as our major achievement in due course.
In my plot we found very little grubs around 30,in samples but about 40 eggs were collected from different spot.Dr.Kumar told that this is a cause for concern.And he asked to carry insecticide application this year too.I hope that this will be the last insecticide application to control rootgrub problem.

Emergence of the beetle
I had been asked by Dr. Prakash to keep record of the rainfall this year.Not the amount of rain but the date of it.Earlier someone told that beetles emerge exactly after two inches of rain.Whether it is in inches or centimeters I don't remember now.This year first rain came on 29 march.About 15 minutes of rain that I consider equivalent to one time irrigation.Second good rain came on10 April.Beetles started to emerge after 7 April.After 18 April we had very good rain almost everyday for about a week.I went to the plot for a few day's in the evening to observe the beetle activity.
I failed to observe beetles in the plot.But there are a lot of beetles nearby rubber plantation.The beetles which we found was not Burmistry.Those beetles were smaller than burmistry and may be grey [or brown]colour.Another limitation for me to observe beetles was that my plot has filled with grass.
Don't understand how those people-Begane Kadappa Gowda,Agali Nagesh Rao collects beetle in their plot.

The farmer's program in Nada village
This is how they conducted a farmer's training program at farmer's plantation
A farmer's training
After a long time I have a wish to write something.Two month's back I had participated in a training program conducted by C.P.C.R.I.Vittal.The program was held at Mr.Prabhakara Maiyya's plot in Nada village ,Belthangadi Taluk.
In my opinion any training in agricultural field must be done in the plantation itself.But although this training was in a farmers plot they built a closed room with shamiyana and for enough air circulation fan's were running.Dr.Ravi Bhat started the discussion and gave a few important notes on arecanut farming.I am concerned with two thing's.One to learn cocoa pruning and another to see what Prabhakar did in his plot to control root grub.Earlier he talked in one radio program about root grub control.
After Ravi Bhat finished his talking's Entomologist Dr.Keshava Bhat took the microphone.Incidentally he had to talk about root grub control.He said that first we have to remove everything from the basin of the plant.Then about 10-15 liter's of chloropyriphose with water in the ratio 5ml per liter shall be poured in the basin.This must be done in the month of May and September,two times in a year.That means 50-75ml insecticide per plant per application.I am glad that I had to use only 4ml per plant per year in one application.
Later Mr.Maiyya talked about his experimentation with root grub control.According to him he came to know about the problem when the workers reported that the grass in the plot was dying.Death of the grass due to root grub and not of the arecanut plant's.I read in some American website that grub affects grass in the golf club. In my plot I have enough grass and I never observed this death of the grasses.That too in the month of May.According to my observation the problem show's it self after the rainy season has ended.In the month of May ,that is after a few rains, plant's start to become greener and healthy.May be I am wrong because my knowledge is very limited,MAY BE HE IS A FRAUD TELLING LIES.
Mr.Prabhakara Maiyya was declared as the best arecanut farmer in Dakshina Kannada district for the year 2010 by the C.P.C.R.I.Vittal and got a felicitation at Krishi Mela held at G.K.V.K. Bangalore

The Mystery
Yes, I said that root grubs in my plot is reducing.But how? Is it from the insecticide application? If it is so from which insecticide?
Last year my plot was divided into six parts and each part had different insecticide treatment.Amongst them one part was left untreated.This year we could see reduced number of grubs in the whole plot.Even in the plot where no insecticide was applied,grubs number is reduced.Then the question remains-which insecticide did the wonders? I do not know. I think that if the methodology and time is maintained any good soil insecticide will do the work.It is for the scientists to explain.
One thing must be clarified.Still grubs are there in my plot.If the treatment last year was a failure young larvae of the last year will grow to adult and we could find a large number of third instar or adult grub this year.If the treatment was a success young larvae's of that year would die,but adult grubs will remain.That grubs will go to pupa stage and then became beetle.The beetles will emerge from the soil in the month of May or June and will lay eggs in the soil. Larvae's will emerge from the eggs later and hence we have young larvae's in the plot.When we say that reduced number of grubs we mean reduced number of grown grubs.
Then what is the effect of nematodes in the plot? Earlier I said that I had seen dead grubs in the plastic basket due to nematodes. But the problem is we cannot find dead grubs in the plot.Because if any grubs died in the plot it will decompose in the soil.Then how can we attribute reduced number of grubs to nematodes?Even with the nematodes,as Dr.Nagesh told adult grubs would not die easily.
Even if the grub problem seems to be reduced and I am now very happy person several questions were unanswered.Normally when I say grub problem is controlled I face one question-which insecticide did it? Frankly I could not answer.

SMELLING SUCCESS
As I was waiting for the scientists to visit my plot,Dr.Nagesh came in the month of July.He brought nematodes with him to apply.Along with my plot he applied them in the plot of Ashoka Bhat,Mairaje's plot too.
After one week Dr.Kumar sir along with Dr.Prakash and Papanna came.They went to Jagajeevan Rao's plot and gave suggestion to him in controlling the root grub.His plot is waterlogged and they asked him to immediately fork the land and remove the grubs manually.Afterwords he shall apply Imidacloprid to his plot.Then they went to Mairaje Ashoika Bhat's plot . There they could not collect enough grubs . Afterwords they came to my plot .We find very little grub activity this year.If the first application of the chemical was a failure we must had a large number of adult grubs in the plot. But what we had is only small[first instar] grubs. Very few adult grubs were seen. Scientists were pleased with the result. Dr. Kumar sir said that second application is not necessary.But to avert any human error in the sampling procedure ,they asked me to do second application. This year his preference is fipronil insecticide.
Arranging workers is another story. But however workers came this week and I started the work.I need a little more days to complete the application.Even workers too,who had seen my plot earlier,agrees to the fact that the plot is improved a lot.
Earlier we applied 20ml of chloropyiriphose per plant without success. But this year we could smell success with only 4ml chloropyiriphose per plant.This itself shows that timing and methodology of application is very important in controlling the grub problem.

Inital result
I could not write anything for a long period,because I didn't had mood for that.In addition to that what I could write is the result of the treatment. After the treatment ,in the month of September Dr.Prakash of G.K.V.K.Bangalore came to the plot and searched for grubs.He declared that grub population was decreased very much and the treatment was a success. But I had my own doubt .The plot was treated with six different methods using five chemicals.Further a portion was kept untreated In which chemical the control was the highest ? In my opinion the plots treated with chloropyriphos,phipronil,imidacloprid and a mixture of imidacloprid and fipronil gave good result.But the surprise element is that grubs in the untreated plot also reduced. But how? A month after Kumar sir also came and searched for the grubs.He also said the same thing.He was satisfied with the result.He gave one clue for my doubt.Whenever we searching for the grubs we destroy the grubs which we collected.In this way a good number of grubs were eliminated from every plot.
Kumar sir asked me to carry the work of forking the land to collect remaining grubs. I could arrange the workers only in the month of December .We got on an average one grub per plant in the plots which were treated with either chloropyriphos,fipronil,imidacloprid.In other plots and untreated plots we got three grubs per plant. Scientists may differ with me ,because they say every C-shaped grub need not be root grub but we farmers consider it as root grub.But any how the number of grubs is considerably reduced is certain.
Now I am confident of controlling grub problem. This confidence came after ten years ,after frustration,after humiliation in the society.Thanks to Kalam sir and the Scientists who were responsible for this.
Months passed and in the month of May I wanted to remove the existing banana plants and replant it.Workers said that when they remove the banana plants they found a few ,three to four ,grubs in it.This helped to understand the still grub infected areas.And this activity removed a huge number of grubs from the plot.
Now I think that second application of the pesticide is necessary this year.And this will bring the grub problem completely under control.Yet to see what Kumar sir says.Another interesting feature is that we found the number of beetles coming to the light in the night is drastically reduced this year.Whether this has anything to do with our treatment I don't know.
