Weed treatment systems

An agricultural sprayer, comprising:

• a first tank having a first tank capacity for holding a first product to be sprayed;
• a second tank having a second tank capacity for holding a second product to be sprayed;
• a product application system including a plurality of selectively actuatable applicator mechanisms configured to apply the first and second products on a field;
• an imaging system configured to obtain image data indicative of plant matter on the field;
• and
• a control system configured to:
• receive a weed distribution model for the field, the weed distribution model including information corresponding to a weed distribution as a function of geographic location within the field;
• identify a remaining portion of the field which has not yet been sprayed with the first product and the second product;
• estimate a first estimated quantity of the first product from the first tank and a second estimated quantity of the second product from the second tank required to complete the spraying of the remaining portion of the field based at least in part on the weed distribution model;
• display the first estimated quantity and the second estimated quantity on a display observable by an operator of the sprayer so that the operator may load the first tank and the second tank with amounts of the first and second product, respectively, sufficient to complete the spraying of a remainder of the field with the first tank and the second tank being empty, at least to a threshold level, at an end of the field;
• detect a presence of weeds of a first weed type ahead of the sprayer and selectively spray the weeds of the first weed type with the first product;
• and
• detect a presence of weeds of a second weed type ahead of the sprayer and selectively spray the weeds of the second weed type with the second product.
