METHOD FOR IMPROVING THE RAINFASTNESS OF BENEFICIAL MICROORGANISMS
The present invention relates to a composition comprising at least one beneficial microorganism and at least one guar gum. It relates more especially to the use of at least one guar gum as a rainfastness agent in a composition comprising at least one beneficial microorganism.
1 . A method for improving rainfastness of at least one beneficial microorganism on an agricultural target or treating a plant infection comprising the step of combining or applying together said beneficial microorganism with at least one guar gum on said agricultural target.
2 . (canceled)
3 . The method of claim 1 , wherein said method comprises at least the following steps:
providing a guar gum,
combining said guar gum with at least one beneficial microorganism to obtain the solution and
spraying the resulting solution on the agricultural target.
4 . The method of claim 1 , wherein said method comprises at least the following steps:
spraying a solution containing a guar gum of the invention on the agricultural target, and simultaneously or successively,
spraying a solution containing one beneficial microorganism on the agricultural target.
5 . (canceled)
6 . A method to increase bioefficacy of a beneficial microorganism comprising the step of (i) combining or applying together said beneficial microorganism with at least an effective amount of one guar gum and subsequently (ii) submitting said beneficial microorganism to exposure to water.
7 . (canceled)
8 . The method according to claim 1 , wherein said guar gum is crosslinked.
9 . The method according to claim 1 , wherein said guar gum has an average molecular weight of between about 100,000 Daltons and 2,000,000 Daltons.
10 . An agricultural composition comprising at least one guar gum and at least one beneficial microorganism, with said guar gum being present in a sufficient amount to improve rainfastness of said beneficial microorganism on an agricultural target.
11 . The composition according to claim 10 , wherein said guar gum is crosslinked.
12 . The composition according to claim 10 , wherein said guar gum has an average molecular weight of between about 100,000 Daltons and 2,000,000 Daltons.
13 . The method according to claim 1 , wherein said at least one beneficial microorganism is a biopesticide.
14 . The method according to claim 6 , wherein said at least one beneficial microorganism is a biopesticide.
15 . The method according to claim 1 , wherein said guar gum is crosslinked.
16 . The method according to claim 1 , wherein said guar gum has an average molecular weight of between about 100,000 Daltons and 2,000,000 Daltons
