Lipo-chitooligosaccharide compositions for enhancing plant growth
Disclosed are compositions for enhancing plant growth, comprising at least one lipo-chitooligosaccharide (LCO) compound; and at least one agriculturally beneficial agent selected from the group consisting at least one pesticide, at least one beneficial microorganism, and combinations thereof. Methods for enhancing plant growth and treating seeds with the compositions provided herein are also disclosed.
1. A method comprising applying
(a) Trichoderma virens GI-3 and
(b) the lipo-chitooligosaccharide represented by structure (V):
or the lipo-chitooligosaccharide represented by structure (VII):
to a plant seed in amounts effective to synergistically enhance one or more growth parameters of the plant that grows from said seed vis-à-vis separate application of (a) and (b),
wherein said method does not comprise application of lipo-chitooligosaccharides from distinct microbial genera,
wherein said method does not comprise application of Bacillus amyloliquefaciens or Burkholderia.
2. The method of claim 1 , wherein said one or more growth parameters comprises shoot length and/or shoot surface area.
3. The method of claim 1 , wherein said one or more growth parameters comprises root length and/or rot surface area.
4. The method of claim 1 , wherein said plant seed is leguminous.
5. The method of claim 1 , wherein said plant seed is a soybean seed.
6. The method of claim 1 , wherein said plant seed is non-leguminous.
7. The method of claim 1 , wherein said plant seed is a corn seed.
8. The method of claim 1 , wherein said Trichoderma virens GI-3 is applied to said plant seed at a rate of about 1×10 5 colony forming units (CFU) per seed.
9. The method of claim 1 , wherein said lipo-chitooligosaccharide is applied to said plant seed at a rate of about 1.86 μg per cwt.
10. The method of claim 1 , wherein the lipo-chitooligosaccharide represented by structure (V):
is applied to said plant seed.
11. The method of claim 1 , wherein the lipo-chitooligosaccharide represented by structure (VII):
is applied to said plant seed.
12. The method of claim 1 , wherein the lipo-chitooligosaccharide represented by structure (V):
is applied to said plant seed at a rate of about 1.86 μg per cwt.
13. The method of claim 1 , wherein the lipo-chitooligosaccharide represented by structure (VII):
is applied to said plant seed at a rate of about 1.86 μg per cwt.
14. A composition comprising
(a) Trichoderma virens GI-3 and
(b) the lipo-chitooligosaccharide represented by the structure (V):
or the lipo-chitooligosaccharide represented by the structure (VII):
in amounts effective to synergistically enhance one or more growth parameters of a plant when said composition is applied to said plant and/or to the seed from which said plant is grown vis-á-vis separate application of (a) and (b),
wherein said composition does not comprise lipo-chitooligosaccharides from distinct microbial genera,
wherein said composition does not comprise Bacillus amyloliquefaciens or Burkholderia.
15. The composition of claim 14 , wherein said one or more growth parameters comprises shoot length and/or shoot surface area.
16. The composition of claim 14 , wherein said one or more growth parameters comprises root length and/or rot surface area.
17. The composition of claim 14 , wherein said composition comprises the lipo-chitooligosaccharide represented by structure (V):
18. The composition of claim 14 , wherein said composition comprises the lipo-chitooligosaccharide represented by structure (VII):
