Embodiment 1

[0018] Example 1 Composite composition to barnyard grass indoor bioassay

[0019] Test object: Barnyardgrass

[0020] Test method: soil spray treatment. 12 hours before treatment, sow the weeds evenly and uniformly at 100cm 2 In the pot, cover the soil with water until the soil moisture is saturated, and then place it in a ventilated hall for treatment. The test treatment was carried out in a well-ventilated hall, and the blank control was treated first, and then the test agent was treated. Spray device setting: spray pressure 1.95kgf / cm 2 , spray volume 50ml / m 2 , Nozzle height 45cm. After treatment, place them in a ventilated hall for 2-3 hours and then move them to the greenhouse for routine cultivation. In the following 15 days, the fresh weight control effect of barnyardgrass was investigated; the experiment was repeated three times.

Abstract

The invention belongs to the field of pesticides, and in particular relates to a ternary herbicidal composition containing bicyclosulfotrione, the active ingredients of which include bicyclosulfotrione, pyrizachlor and pretilachlor; the weight ratio is 3‑18:0.9‑3.6: 18‑54; can be used for the control of weeds in paddy fields, compound use can slow down the emergence of weed resistance, reduce the dosage of a single dose, and have a synergistic effect.

Description

technical field [0001] The invention belongs to the field of pesticide preparations, in particular to a ternary herbicidal composition containing bicyclic sulcotrione. Background technique [0002] Bicyclic sulcotrione is an inhibitor of p-hydroxyphenylpyruvate dioxygenase (HPPD) developed by Shidishi in Japan. It affects the synthesis of plastoquinone by inhibiting HPPD, and then dehydrogenates phytoene by plastoquinone. Enzyme (PDS) action, which ultimately affects the biosynthesis of carotenoids, resulting in leaf bleaching. It is a selective herbicide, which is absorbed through the roots and stems of weeds, and then transmitted to the whole plant. It is used before and after seedlings to control annual and perennial weeds in direct-seeded rice fields and transplanted fields. [0003] Pyrimifluben belongs to the class of pyrimidine (thio) benzoate herbicides and is an inhibitor of acetolactate synthase. Pyrifluben can be applied from the pre-emergence to the late post-e...
