Methods and compositions for improving plant health

摘要

The present invention provides methods and compositions for improving plant health. In particular, application of dicamba or another substrate of DMO, or metabolites thereof including DCSA, to a plant confers tolerance to, or defense against, abiotic or biotic stresses such as oxidative stress including herbicide application, and plant disease, and enhances crop yield. Such application may be in combination with the application of another herbicide such as glyphosate.

主权项

1. A method for increasing the germination rate of a seed, comprising:
(i) contacting the seed with 3,6-dichloro salicylic acid or an analog thereof in an amount that improves the germination rate of the seed as compared to a seed of the same genotype not contacted with 3,6-dichloro salicylic acid or an analog thereof; or (ii) contacting a seed with dicamba in an amount that improves the germination rate of the seed as compared to a seed of the same genotype not contacted with dicamba, wherein the seed contacted with dicamba is a transgenic seed comprising a DMO-encoding transgene; wherein the amount that improves the germination rate of the seed is about 0.1 grams to 100 grams of 3, 6-dichloro salicylic acid, or an analog thereof, or dicamba per 100 kilograms of seed.
