Abstract
Abstract The invention provides a method for fumigating grain stored in bins by the gravity penetration method comprising applying methyl-bromide and liquid CO 2 to the upper layer of grain stored therein wherein the liquid CO 2 is applied to said upper layer of grain through a conduit having an inner cross-sectional area at least about twelve times as great as the cross-sectional area of the outlet.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
147 words
A method for fumigating grain stored in a bin by the gravity penetration method comprising applying methyl-bromide to the top of said bin and spraying liquid CO 2 at the top of said bin at the upper layer of grain stored therein by providing a liquid CO 2 container with a delivery conduit in fluid communication therewith and providing said delivery conduit with an outlet remote from said container wherein the inner cross-sectional area of said conduit is at least about 12 times as great as the cross-sectional area of said outlet and passing liquid CO 2 from said container through said delivery conduit to the outlet of said delivery conduit under such conditions that liquid CO 2 emerges from the outlet and flows without the formation of solid CO 2 in gaseous form by gravity together with the methyl bromide to the bottom of the bin.
Claim 2
Independent Claim
147 words
A method for fumigating grain stored in a bin by the gravity penetration method comprising applying methyl-bromide to the top of said bin and spraying liquid CO 2 at the top of said bin at the upper layer of grain stored therein by providing a liquid CO 2 container with a delivery conduit in fluid communication therewith and providing said delivery conduit with an outlet remote from said container wherein the inner cross-sectional area of said conduit is at least about 12 times as great as the cross-sectional area of said outlet and passing liquid CO 2 from said container through said delivery conduit to the outlet of said delivery conduit under such conditions that liquid CO 2 emerges from the outlet and flows without the formation of solid CO 2 in gaseous form by gravity together with the methyl bromide to the bottom of the bin.
Claim 3
Dependent Claim
59 words
A method according to claim 1, said liquid CO 2 container being provided with a dip pipe, said delivery conduit being attached to the outlet of said dip pipe and in fluid communication therewith, further comprising passing said liquid CO 2 from said container through said dip pipe and said delivery conduit to the outlet of said delivery conduit.
Claim 4
Dependent Claim
25 words
A method according to claim 1, wherein the ratio of inner diameter of the conduit to the diameter of the outlet is 4:1 to 20:1.
