The invention relates to a method for treating a plant wherein an agrochemical composition is applied onto at least one part of said plant, wherein the plant is corn or soy and wherein the agrochemical composition comprises in a liquid medium: particles of at least one inorganic phosphor exhibiting: a maximum in the emission spectrum in the range of wavelengths between 400 nm and 500 nm; an absorption Abs in the visible range which is equal to or less than 15.0%, preferably equal to or less than 10.0%, even more particularly equal to or less than 3.0%; and an internal quantum efficiency (IQE) measured in the range of wavelengths between 300 nm and 410 nm which is equal to or greater than 50.0%, more particularly greater than 75.0%, even more particularly greater than 90.0%;
and optionally at least one biocide.

Herbicides, systems, and methods for inhibiting germination of a root parasitic plant are provided. In particular, the herbicide includes an active compound represented by Formula I. In this regard, the active compound is selected to bind to an active site of strigolactone receptors in seeds of the root parasitic plant.

Methods of producing sugar cane transplant units that includes planting a sugar cane propagation material in a planting container that has a volume of 10 to 200 cubic centimeters; growing the sugar plant to an age of at least 4 months; harvesting the stalks of the sugar cane plant when the stalks have a length of 10 to 50 centimeters; cutting the harvested stalks into stalk segments, wherein the stalk segments are cut to a length of 1 to 5 centimeters; and planting one or more of the stalk segments into a planting container that has a volume from 10 to 200 cubic centimeters.

Systems and methods are provided for use in applying treatments to crops in fields. One example computer-implemented method includes calculating a growth stage of a crop in a field on a defined date based on planting data and weather data for the field and/or crop, and then, in response to the growth stage being within a spray window for the crop, defining a plurality of synthetic sprays within the spray window for the field. The method then includes, for each one of the synthetic sprays, calculating at least one disease risk for the crop in the field and calculating a response to the synthetic spray. The method then further includes compiling a report including a selected one or more of the responses, based on yield differences of the responses, as a recommendation for applying the treatment to the crop consistent with the synthetic spray associated with the selected one or more of the responses.

A method and a system for diagnosing a plant disease and an insect pest are provided. The method includes: obtaining an plant image; determining a candidate specie and candidate disease and insect pest information corresponding to at least part of the candidate specie according to the plant image when a current diagnosis mode is a passive diagnosis mode; screening out the candidate disease and insect pest information of the candidate specie according to a first preset condition for the candidate specie with the corresponding candidate disease and insect pest information; and outputting at least part of remaining disease and insect pest information after screening out when there is the remaining disease and insect pest information.
