Applicants have developed novel methods and compositions for treating, preventing or ameliorating the effects plant phytopathogen infestation in plants, including ofLiberibacter spp. the causal agents of citrus greening and potato zebrachip disease. Novel compositions include one or more active agents of aminocaproic acid, carbinoxamine maleate, chloroxylenol, chlorpropamide, cinoxacin, duartin, and cyclopentolate hydrochloride as well as their derivatives, or salt/acid forms thereof. Methods of preventing disease development and infestation by plant pathogens are disclosed as well as methods of making, using and producing such compositions.

Applicants have developed novel methods and compositions for treating, preventing or ameliorating the effects plant phytopathogen infestation in plants, including ofspp. the causal agents of citrus greening and potato zebrachip disease. Novel compositions include one or more active agents of aminocaproic acid, carbinoxamine maleate, chloroxylenol, chlorpropamide, cinoxacin, duartin, and cyclopentolate hydrochloride as well as their derivatives, or salt/acid forms thereof. Methods of preventing disease development and infestation by plant pathogens are disclosed as well as methods of making, using and producing such compositions.

Numerous plant microbes, including the vascular-limitedspp.&#x2014;causal agents of citrus greening and potato zebra chip diseases&#x2014;are non-culturable. The present disclosure relates, according to some embodiments, to compositions, methods and systems for culturing such organisms. For example, the present disclosure relates to methods for culturing, propagating, and characterizing fastidious vascular-colonizing microbes using a hairy root system (e.g., in vitro, in planta). The present disclosure relates, in some embodiments, to methods for cultivating a fastidious plant microbe including: contacting a plant (e.g., a tomato plant, a potato plant, a citrus plant) colonized by a fastidious plant microbe (e.g.,Liberibacter spp.) with a suspension ofunder conditions that permit induction of hairy roots colonized with the fastidious plant microbe, and propagating the colonized microbial hairy roots.
