HOW TO GET RID OF 



GRASS? 



ILLUK 



Batticaloa, March 1st. 

 Dear Sir, — In your paper recently I notice 

 a correspondent writing about the destruction 

 of illuk grass on Mr. Nicholas's estates. Would 

 ycu be so kind as to get the information from 

 Mr. Nicholas or your correspondent how to get 

 rid of the illuk, as we have a great quantity 

 here and would like to know how it is destroyed ? 

 — Yours faithfully, 



JOHN COTTON. 



Mr. G. T. Nicholas's Methods. 

 Golua Pokuna, Katunayaka, March 10th. 



Dear Sir, — Absence from home has delayed 

 my responding to the call made on me, in your 

 issue of the 4th instant, in reference to Mr. John 

 Cotton's letter, asking for information as to how 

 to get rid of Illuk grass. 



Just three years ago (5th March, 1906), the 

 Hon. Mr. J. Ferguson, c.m.g., read a paper, at 

 the meeting of the Board of Agriculture, on 

 " Illuk or Lalang Grass : a tropical weed pest, 

 with measures for combating it," supplemen- 

 ting his paper with one by myself "On a Simple 

 and Inexpensive Method of Suppressing and 

 Exterminating Illuk over large areas in Coconut 

 Plantations." These, with other connected papers, 

 were published jn full in the May 1906 number 



of the "Tropical Agriculturist" and I refer Mr. 

 Cotton to the magazine for full details of ray 

 methods and results. 



The idea of growing certain plants to keep 

 down Illuk Grass appears to have " caught on" 

 for we now read of l assiflora foztida being used 

 in the Malay States for suppressing the pest. 

 But, in my opinion, this plant is less suitable 

 than the Madi. vel {Sink.) which is of a more 

 robust habit of growth ; if the latter be grown 

 along with the shrub known to the Sinhalese 

 as Ptipula, the Illuk is soon got under. 



The tendrils of the Madu vine attach them- 

 selves to the blades of Illuk and draw them 

 down, while the thick close growth of the Pupula 

 shrub completely shades the ground and helps 

 to choke out the weed grass. 



I shall be glad to give Mr. Cotton any further 

 information on this subject and also to send him 

 seeds of the above-mentioned plants, if he will 

 communicate direct with me. 



Treatment with "Arseniteof Soda" is said 

 to have proved very successful in experiments 

 made in Selangor, but I have never tried it as I 

 have been quite satisfied with the efficacy of my 

 own method which is devoid of any element of 

 danger. "Arsenite of Soda" being very poisonous, 

 care must be taken that no cattle eat the treated 

 grass. 



The method of preparation and application 

 of the solution is as follows: — " 2'88 lb. of 

 washing soda are dissolved in 3 gallons of water 

 and boiled ; then 2 lb of white arsenic are 

 slowly stirred in, the liquid being kept boiling 

 till all the arsenic is dissolved. It is then 

 diluted to 20 gallons as a stock solution." 



"Two pints of this are diluted with five gallons 

 of water aud this is sprayed on the grass, or it 

 can be put on by moans of a cloth, one end of 

 which dips in a trough on wheels containing the 

 solution, the other trailing on the grass and kept 

 open by means of an iron rod." 



"The grass can be first burned off. When 

 new shoots are 8" to 9" long the wet cloth is 

 drawn over them which kUls the shoots in 48 

 hours. This is repeated each time new shoots 

 appear, the object being to exhaust the roots of 

 all starchy matters aud so kill the plants en- 

 tirely." — Yours faithfully, 



GERALD T. NICHOLAS. 



RUBBER NOTES. 



Close Planting of Rubber.— With regard to 

 distance in planting it is of interest to record 

 that on Caledonia Estate 378 lb. of dry rubber 

 per acre was obtained in one year from seven 

 year old trees, planted 10 feet by 10 feet. — W J 

 Gallagher. -for March. 



Rubber Growing in the Seychelles.— A 

 correspondent in Seychelles informs us that 

 Para rubber is thriving exceedingly well in that 

 part of the world, but that Funtumia, C'astilloa 

 and Ficus are by no means proving successful. 

 It appears that Funtumia and Castilloa in Sey- 

 chelles suffer very much from parasites, especi- 

 ally scale insects.— Jndia-Rubber Journal, Jan, 25.
