the preferred range of concentrations or hydrogen peroxide for use in intermittent treatment of foodstuff and plant matter in accordance with the process of the present invention is from 0 . 001 % to 50 %, preferably from 0 . 01 % to 20 % and more specifically from 0 . 1 % to 15 %. the preferred range of concentrations for continuous or short interval treatment is 10 ppm to 40 %. the range of concentrations of dispersed metal and / or metal ion for use in accordance with this invention is from i ppb to 5 %, preferably from 10 ppb to 10 , 000 ppm , more specifically from 20 ppb to 2000 ppm and even more specifically from 20 ppb to 1000 ppm . the combination of hydrogen peroxide with appropriate metal ion ( s ) provides in certain instances a synergistic effect by which the hydrogen peroxide effect is enhanced . in addition , the minute trace residue quantities of the metal ion ( s ) have been found to have a slower but longer lasting beneficial effect on the prevention of quality and quantity deterioration of foodstuff and plant matter . the treatment of the treated matter in accordance with this invention can be implemented satisfactorily in various ways . these include , in certain cases dipping the treated matter in the above mentioned solution ( s ) or spraying the solution ( s ) onto the treated foodstuff or plant matter . however it should be pointed out that water or condensed water droplets on the surface of foodstuff and plant matter can enhance the proliferation of pathogens and thus have a detrimental effect . this is of particularly concern when it is important to maintain storage conditions of high relative humidity , such as in the storage of potatoes , to prevent material loss due to evaporation and other forms of deterioration induced by a low humidity environment . intermittent treatment by means of the process and compositions of the present invention , protects foodstuff and plant matter so treated from adverse effects of condensation of water on the surfaces of the foodstuffs and plant matter , so treated . the application of the solution in the form of ultra small drops by solution atomizing systems that produce “ dry ” fogs with particle sizes of less than and up to 1000 microns in diameter , has been found to provide particularly beneficial results . these include compensation for or prevention of water loss , inhibition of sprouting , rot inhibition , less overall losses and higher yields for treated seeds . the beneficial results include epical dominance breakdown . the advantages of small particle size “ dry ” fog is attributed to the fact that very small particles behave to a large extent like a gas . they facilitate the achievement of very high relative humidity , i . e ., even as high as 99 %+, without any condensation on the stored matter . furthermore , the small particles show a very high penetrability into small cracks and spaces . as a consequence , even when potatoes are stored in ordinary stacks or storage sacks , the “ dry ” fog storage has a high degree of penetrability and accessibility to all points in the stack or sack . this means that even in the simplest and most space compact facilities stored plant matter , such as potatoes and similar items , can be effectively treated to prevent weight loss due to dehydration as well as softening and other deteriorative processes brought about by an inadequate humidity environment . another benefit of the “ dry ” fog is that it allows higher concentrations of hydrogen peroxide and other active ingredients to be used without causing damage to the protective peel or surface of the plant matter so treated . the higher concentration of treating solutions enhances their effectiveness in the rapid elimination of pathogens . when the foodstuff and plant matter is treated by dipping or ordinary spraying , the optimal hydrogen peroxide concentration should be substantially between 0 . 5 %- 1 . 5 % and treating time between a few seconds up to a few minutes . when the treatment is applied as a “ dry ” fog , the hydrogen peroxide concentration may be up to 40 % and the time of application from several hours to a number of days . a further benefit of application by fog is that it allows for convenient adjustment of the carbon dioxide - oxygen balance in the storage room or chamber , thus inhibiting “ black heart ” deterioration . preferably , the air to liquid volume ratio in the fog should be between 300 : 1 and 1200 : 1 , more preferably between 500 : 1 and 700 : 1 . in certain aspects and applications , the beneficial effects of the process of the present invention are enhanced by the addition of certain additives to the treatment solution , these additives may include : stabilizers and modifiers such as but not limited to , citric acid , tartaric acid , boric acid , bromic acid , stannates , phosphonic acids etc . ph regulators , primarily mineral and organic acids , such as but not limited to phosphoric acid , peracetic acid , hydrochloric acid , sulfuric acid , etc . for optimum effectiveness , the ph should be lower than 6 and preferably between 1 - 4 . trace element activators , synergists and promoters , such as but not limited to , dispersions of metal , non - metals or ions ( of various valences when appropriate ) such as , copper , zinc , nickel , iron , potassium , manganese , silver , chromium , molybdenum , magnesium , boron , phosphorus , iodine , sulfur , citrate , etc . organic or inorganic additives , such as but not limited to , peracetic acid , phenol , gelatin , glycerin , sodium azide , polymoxin b , sodium bicarbonate , pectin , salicylic acid , etc . in several experiments conducted in a storage room containing hundreds of metric tons of potatoes , a hydrogen peroxide - metal ion solution was introduced with a fogger overnight until a relative humidity level of 80 - 99 % was attained the potatoes were kept in the storage room for 5 months , during which time fogging treatment was effected 10 - 50 % of the time . the result of the spraying was that losses due to disease were reduced from 8 % to 2 %, while losses due to dehydration were reduced from 5 % to 2 %. therefore the total loss reduction was from 13 % to 4 . 5 %, a net average reclamation of 8 . 5 %. the effect of treatment with various solutions of aqueous hydrogen peroxide plus additives at the following concentrations : 0 % ( control ) and 0 . 1 %- 30 %, by dipping for various lengths of time . clear - cut sprout inhibition was obtained for bulbs so treated , compared to the control , as well as decay prevention for extended time . in certain concentrations , an opposite result was obtained , of rot and severe phytotoxic damage to the tubers . each of the treatments were repeated five times . each time involved 50 kilograms of potatoes . same as example 2 , except that instead of dipping , the solutions were sprayed onto the foodstuff substrate until dripping ( high volume ). same as example 3 , except that the spraying onto the foodstuff substrate was low volume . same as example 3 , except that the spraying onto the foodstuff substrate was ultra low volume . same as example 3 , except that the spraying onto the foodstuff substrate was by fogging . the gas liquid volume ratio was 600 : 1 . each of the treatments described in examples 2 -
