FIRE and WEED CONTROL

You have now entered into an on going war with grass and weeds, Scrub cutters [weed wackers] will be constantly on the go and you will need to poison.

Nice one Jim, i am sure this thread will keep getting bumped if it doesnt get pinned.

With you mentioning weed killer (poison) are you using Glysophate (roundup) or have you another method besides brushcutting ?

Mark I presume

Think you just illustrated one of my points. I have no idea what poison they use. As with any job that reguires a special skill or knowledge, I hire a man who knows.

IA only thing I know about pigs is that I hope to come and eat one of yours this year.

To all,

If your plantation(s) is/are big enough buy a tractor with a 1.2 - 2m weed cutter operated off the PTO. Just read an article in the BKK Post stating that the use of chemicals in the farming industry are to be cut - one can only pray!!! Try not to use any chemical weed killers....

I use Glysophate to control the grass and weeds but not untill the trees are 4 years of age. It takes usually 3 applications of the stuff and I don't go anywhere near it. I have one guy that is very experienced in using it and I let him get on with it. Up untill 4 years I can cultivate between the rows with the tractor and hire people to hand weed between the trees.

Gylsophate is a user friendly chemical as far as herbicides go and the beauty of it is you can apply in small doses and it accumulates,

ie you can give 150ml dose and if weed is not dead apply another dose of 150ml and it equal a 300ml dose.

Gylsophate is your friend dont over apply rates as you will create resistance then you will be forced to use more expensive and less friendly herbicides.

Paraquat on the other hand is not user friendly and does not accumulate with doses however is the right application if you want to spraytop pasture to stop seed set and maintain a ground cover to stop erosion.

Nice looking trees Kwonitoy, but as for my preference, I like to have a bit of grass / weed cover in between the trees with a 1.5 m radius around the trees weed free. This helps slow erosion and is more pleasant to walk on than mud in the wet season.

Nice uniformity of trunk size there Kwonitoy. Are they Rimm 600's ?

I am tempted to use Glysophate, but i am wary of the long term effects of the stuff. If you believed everything you read about Monsanto you would perhaps understand my trepidation.

The trees have a lot of surface roots due to their age (20 year) and are therefore susceptible to damage from a tractor driven cutter so i cant use that option. Additionally the roots are more likely to come into contact with the Glysophate as well, being that many are near the surface.

I presume the Glysophate becomes inert when it binds to the soil, but its that age old question of wondering if there is any long term detriment lurking inside this herbicide.

Has anyone had any bad experiences with Roundup ?

Thanks guys:

They are RIMM 600 varity trees,

SB you raise a good point about erosion and future tappers walking around. To date there is no noticable erosion, and we've been getting a lot of rain lately. It makes me think about leaving a little greenery on the next pieces to get sprayed.

I would wonder also if the trees accumulate the Glysopaphate, I would imagine they would have to absorb some but perhaps dissapte it because of their size. At 4 years of age when they were sprayed the surface roots aren't so noticable. I don't know about spraying trees that are older and have more roots spread out.

Personally I'm not a big fan of chemical control, the wife wanted to spray for weeds when the trees were 2 years old and I just don't think that's good for young trees that are still in rapid growth. I paid for cutters and did a lot of hand cutting myself untill it just got to be to much. There were some replants in amoungst the older trees and the spraying did kill some of them.

If you believed everything you read about Monsanto you would perhaps understand my trepidation.

I do understand your concern about Monsanto, I grew up on a Canadian grain farm and dealing with them is like selling your soul to the devil. Once you buy their seeds you're hooked into their very propritory system. But for Thailand I'll buy their chemicals and leave it at that.

Here's 2 of our plantations without any weed chemicals and using organic fertilizers. The trees are 5 yrs. old.

that was very informative Jim. Thanks.

I don't have Rubber myself but have often thought about it. Just don't have the space anymore unless I was to intermix with the current trees which would be a leap of faith .

what organic fertilier do you use scotbeve , just animal shit I guess. !?

Why worry about a few weeds anyway after the trees get so big ? Everyone around my place is spraying with chemicals on everything this year. they used to just do the edges of the ricefields but now its a much cheaper option than the weedwacker due to the price of fuel. It probably isn't roundup either. its got to have dire consequences down the line.

Jubby,

Yes, just crap and when I can get my hands on it, compost. I'm actually selling 18 rai of 5 1/2 yr. old trees if you're interested (I have enough and this was part of my master plan).

I'll have to pass on that Scotbeve. I'm in the middle of an ecomonic mismanagement on a par with one of your fellow scots.

Gordon the moron I think they call him. ;)

hi,

great too see that rubber is getting the attention it deserves here!

alot hard work has gone into the workings of your plantation, the ground and the trees look very good. what is the circumference of the better trees in this plantation?

the few people who i know that are tapping at present all started on trees that were 7+ years old but were at best 45cm at around a metre from the ground. have always thought that waiting for the magic 50cm was best, what do you all think/ size started at if tapping already?

from what i can see most tapping starts above the 80cm mark on the tree, but i have seen some people that have started very close too the ground say around 40-50cm high on good sized trees that would be 50cm+ at 1metre from the gound, any ideas on this???

I add my congrats to you Jim on your humorous and informative primer...

..wifey and in laws have just this week opened up another 600+ trees and they seem to have started at the 800 to one metre level on 45+ cm trees...growth rate seems all over the map in some rows unfortunately...(we bought this part of the farm with these trees at about 3yo).

Wifey et al tapped 3 on 1 off on the mature trees on another part of the farm..now doing the same on new ones.

On the subject of weed control , I read on an Indian state website that clear cut and removal of all weeds/grass is not recommended ( natural moisture retention seemed to be the factor along with erosion)...during all our floods down here thousands of trees on flat land simply fell over due to ground turning to treacle on land with little or no ground cover.

We have sprayed Glyphosphate to get rid of the brush type weeds and now mostly have just that vicious leg cutting grass which we cut every three months or so...seems to grow up behind you as you walk the line though...all that grass mulch has got to be good for the trees methinks. Interestingly some areas just grow some low pretty purple flowered weeds which turn your hands black after you pull a rai or so..lol

Time now to throw some more baht on the ground in the form of fertiliser I guess....

May all your cups runneth over..

cheers

david

On this plot of land (10 rai) the trees are nice and uniform and are an average of 40cms diameter. I have another section that I'll start on this year with some trees being up to 60cms diameter, but its land that we bought already planted and the trees are not so even, kind of a mixed bag of sizes

I'm going to follow the the 50cms diameter, 1 meter off the ground before tapping. I'm expecting to open these trees in two years, although all our neighbors on both sides have begun tapping already. Around our area I see the locals start to cut the trees too young, but they are probably hurting for some payback after 5 or 6 long years of waiting

As I haven't tapped a tree yet this is new territory for me, but we'll start at least 1 meter off the ground
