Embodiment 1

[0015] Example 1 :Indoor Toxicity Test of Triclopyr and 2-methyl-4 Chloride on Broadleaf Weeds

[0016] Test subjects: Amaranthus retroflexus L., Portulaca oleracea L. (collected and stored in the field)

[0017] Test method: The test adopts the stem and leaf spray method. The loam is collected outdoors, dried, crushed, sieved, dried and disinfected for 12 hours for use. Put a certain amount of sieved loam in the seedling tray, suppress and pour water, and accelerate the germination of weed seeds to whiteness. Select weed seeds with the same whiteness and sow them in a nutrient bowl with 25 weed seeds per bowl. The treatment was repeated 4 times. According to the experimental design, the dosage was treated with quantitative spray on the surface of stems and leaves. After being cultured in a greenhouse for 21 days, the aboveground part was taken to weigh the fresh weight of residual weeds, and the fresh weight control effect was calculated. The fresh weight control effect (%) of ...

Embodiment 3

[0025] Example 3 Control effect of triclopyr and 2-methyl-4-chloride on weeds in winter wheat field

[0026] Test object: winter wheat field weeds (Amaranthus variabilis, Portulaca oleracea, Artemisia sowing, Shepherd's purse, Porcini)

[0027] Test method: spray treatment of stems and leaves. The soil in the test field was loam, and the previous crop was summer corn. Random block arrangement, repeat 4 times, the block area is 40m2. During the application period, after the wheat turns green and before jointing, the weeds are at the 3-8 leaf stage. 21 days after the application of the pesticide, the investigation of the fresh weight control effect was investigated. The survey method is sampling at 4 points per plot, 0.25m2 (0.5m×0.5m) per point, calculating the type and fresh weight of the remaining weeds within 1m2, and calculating the fresh weight control effect.

[0028] Test agent:

[0029] 40% triclopyr·methyl 4 chloride wettable powder

[0030] (Formulation: Triclopyr 20%, 2...

Abstract

The invention provides a weeding composition containing triclopyr and chipton. The weight ratio of the triclopyr to the chipton is (1:16)-(16:1). The composition disclosed by the invention can be usedfor preventing and removing weeds such as amaranthus retroflexus, purslane, descurainia sophia, shepherd's purse and cleavers in rice or winter wheat fields, and can be used for reducing the dosage of medicaments and reducing environmental pollution.

Description

Technical field [0001] The invention belongs to the field of pesticides, and specifically relates to a herbicidal composition containing tricclopyr and 2-methyl-4 chloride. Background technique [0002] Triclopyr is a pyridyloxycarboxylic acid systemic herbicide with low toxicity and a hormonal herbicide. It is absorbed by the leaves and roots of plants, and is transmitted to the whole plant in the plant, causing its roots. , Stems and leaves are deformed, the vascular bundles are embolized or ruptured, and the plants gradually die. Gramineous crops have certain resistance to it. It is suitable for pre-forestation and forestry transformation, and for the control of broadleaf weeds and woody plants in non-arable land. It can also be used for the control of broadleaf crops such as wheat, corn, sorghum and other fields. Weeds. [0003] MCPA is a selective hormone herbicide, which has strong physiological activity on plants. It promotes plant growth at low concentration; inhibits gro...
