Embodiment 1

[0036] Preparation of Isoproturon·Bensulfocarb Granules with 10% active ingredient: 5% Isoproturon, 5% Bensulfocarb, 5% calcium lignosulfonate, 4% pull-off powder, 5% starch, 3% ammonium sulfate %, kaolin supplemented to 100% (the mass fraction ratio of isoproturon and procarbocarb is 1:1)

Embodiment 2

[0038]The active ingredient is 20% Isoproturon·Bensulfocarb suspoemulsion: get 6.67% Isoproturon (unit mass percentage, the same below), 13.33% Isoproturon, 4.0% fatty alcohol polyoxyethylene ether, 5.0% % fatty alcohol polyoxyethylene phosphate, 5% polyvinyl alcohol, 20.0% xylene, 1.0% ethylene glycol, 0.05% organic silicon, and the remainder is replenished to 100% with water, prepared by the usual suspoemulsion method of pesticides ( The mass fraction ratio of isoproturon and procarbocarb is 1:2)

Embodiment 3

[0040] The active ingredient is 30% isoproturon·procarba water emulsion preparation: get 7.5% isoproturon (unit is mass percent, the same below), 22.5% procamprocarb, 4.0% fatty alcohol polyoxyethylene ether, 5% fatty alcohol polyoxyethylene ether phosphate, 5% polyvinyl alcohol, 20.0% xylene, 1.0% ethylene glycol, 0.05% organic silicon, and make up the balance to 100% with water, prepared according to the usual water emulsion method of pesticides .

Abstract

The invention discloses a paddy field weeding composition containing prosulfocarb and isoproturon. The composition comprises effective components including the prosulfocarb and the isoproturon, wherein the mass percent ratio of the prosulfocarb to the isoproturon is 1 to (1-8). The composition disclosed by the invention has high complementarity and an obvious synergistic effect, and has the characteristics that a weeding spectrum is expanded, an application dosage is reduced, application suitable time is prolonged, the security for crops is high, the environmental pollution is reduced, and the environmental compatibility is great and the like.

Description

technical field [0001] The invention belongs to the technical field of agriculture, and relates to a herbicidal composition with a synergistic effect, in particular to a paddy field herbicidal composition for controlling grassy weeds, Cyperaceae weeds and broadleaf weeds in paddy fields . Background technique [0002] Prosulfocarb, the chemical name is S-benzyl dipropyl thiocarbamate, is a selective systemic conduction type soil treatment herbicide of thiocarbamate. Sensitive gramineous weed seedlings, the symptoms of damage by thiocarbamate compounds are that the seedlings are dark green, the plants are distorted, the growth of seedlings and roots is inhibited, and the leaves are prevented from coming out from the bud sheaths. For true plants with more than 4-5 leaves Leaf plants, severe necrosis in and around the meristem, soil treatment test studies show that the selectivity of pre-emergent applications for gramineous crops depends on the "deep" protection, analytical re...
