Methods for controlling black sigatoka in bananas using pongamia oil and formulations thereof
The present disclosure relates to methods for controlling black sigatoka, or black leaf streak, disease in banana plants using pongamia oil and formulations thereof. The present disclosure also provides formulations comprising pongamia oil, including emulsions and emulsifiable concentrates, for use in the control of black sigatoka.
1. A method for controlling black sigatoka in a banana plant, comprising:
applying pongamia oil to the banana plant.
2. The method of claim 1 , wherein the pongamia oil is formulated as an emulsion.
3. The method of claim 2 , wherein the emulsion comprises:
one or more non-ionic emulsifiers;
water; and
optionally one or more organic solvents.
4. The method of claim 2 , wherein the emulsion comprises pongamia oil at a concentration of at least 1% v/v, and the weight ratio of pongamia oil to the one or more emulsifiers is between 7:1 and 9:1.
5. The method of claim 1 , wherein the pongamia oil is applied to the banana plant by spraying.
6. The method of claim 1 , wherein the pongamia oil is applied to the leaves of the banana plant.
7. A method for controlling black sigatoka in a banana plant, comprising:
applying a formulation comprising pongamia oil to the banana plant.
8. The method of claim 7 , wherein the pongamia oil is an emulsified pongamia oil.
9. The method of claim 7 , wherein the formulation comprises one or more non-ionic emulsifiers.
10. The method of claim 9 , wherein the one or more emulsifiers are selected from the group consisting of fatty alcohol alkoxylates and polysorbate (polyoxyethylene sorbitan) fatty acid esters.
11. The method of claim 7 , wherein the formulation is an emulsion.
12. The method of claim 7 , wherein the formulation is an oil-in-water emulsion.
13. The method of claim 7 , wherein the formulation is applied by spraying.
14. The method of claim 7 , wherein the formulation is applied to the leaves of the banana plant.
15. The method of claim 7 , wherein the pongamia oil is an emulsified pongamia oil and the formulation comprises the emulsified pongamia oil at a concentration of at least 1% v/v.
