A plant disease control method and a plant disease control apparatus that can irradiate a plant under cultivation with an appropriate amount of near-infrared light to obtain an effect of controlling diseases while efficiently using light energy. The plant under cultivation is irradiated with the near-infrared light including a wavelength set within a wavelength range of 800 to 1000 nm so as to satisfy all following Equations 1 to 3 where X is an irradiance (W/m.sup.2) and Y is an irradiation time (second), so that the effect of controlling diseases can be obtained.

A plant limb training apparatus includes a first portion with a first fulcrum portion, a first portion arm extending from the first fulcrum portion and having a first limb engagement finger, the first fulcrum portion further including an interior race and ratchet teeth around the interior race; and, a second portion, the second portion including a second fulcrum portion, a second portion arm extending from the second fulcrum portion and having a second limb engagement finger, the second fulcrum portion configured to engage the first fulcrum portion within the first fulcrum portion interior race, the second fulcrum portion further including at least one pawl element disposed to selectively engage the plurality of ratchet teeth.

Various embodiments relate generally to computer vision and automation to autonomously identify and deliver for application a treatment to an object among other objects, data science and data analysis, including machine learning, deep learning, and other disciplines of computer-based artificial intelligence to facilitate identification and treatment of objects, and robotics and mobility technologies to navigate a delivery system, more specifically, to an agricultural delivery system configured to identify and apply, for example, an agricultural treatment to an identified agricultural object. In some examples, a method may include, at least, detecting an optical sight to align with an associated agricultural object, tracking the agricultural objects relative to the optical sight, predicting a parameter to track in association with agricultural object, and activating an emitter to apply an action based on the parameter.

A method for the conservative treatment of at least one symptomatic fruit plant showing symptoms of a disease, comprising the steps of identifying the symptomatic plant which has undergone a pruning step; identifying a period of quiescence or a period of resumption of vegetative growth of the symptomatic plant; and during the period of quiescence or resumption of vegetative growth, making at least one hole in the trunk of the symptomatic plant until reaching the xylem; finally, introducing into the xylem, by means of said at least one hole, an amount of treatment fluid such as to provoke the discharge of the same fluid from the pruned portions of the symptomatic plant and/or the discharge of sap from the same symptomatic plant.
