505 is the commercial name of a type of insecticide. useful against trunk borer they said and confirmed by Agriculture Officer.
A method to use is to clear the spot by poking and injecting via the syringe and either wait or cover up with earth.
My planting distance is 10 feet.
Hi Yongbs,
welcome to the club like MrFarmer put it.
All are planted with durians ?? Which clone/clones are they ?
please let us have more details of the farm or more pictures will help

Hi,
I have about 150 trees consist of D2, D24, D144, Kuning("wong yoke chai"), D197 and others which I could not identify. The whole 5 arces planted with durians.
I have felled about 20 nos of D144 coz this clones never ripe properly but the color of the flesh is bronze. All the trees is about 15 years old except my D197 about 3 years old.
Will get some pictures of the farm during my next trip next week.
Cheers.
