Embodiment 1

[0015] Example 1 : Determination of Indoor Toxicity of Propyryloxadiazone and Sizazine on Dracula chinensis

[0016] Test object: Cottonia chinensis seeds (collected in the field, preserved in this laboratory)

[0017] Test method: Greenhouse potting method was adopted. Put the test soil (without chemical treatment) into the flowerpot, add water until the soil is completely wet, and sow the germination-promoted Cormisophyllum seeds in the flowerpots respectively. Soil spray treatment was carried out 24 hours after sowing, and each treatment was repeated 4 times, and a blank control was also set. After the treatment, it is cultivated in the greenhouse, and the bottom irrigation method is used to replenish water regularly to maintain 100% soil humidity. Spraying equipment: ASS-1 pesticide spraying system. After 14 days, the fresh weight of weeds in each treatment was calculated. Using spss software to analyze the data and calculate the ED50 value.

Embodiment 2

[0024] Example 2 Field control effect of propargyl oxadiazone and siquat on weeds

[0025] Test objects: Weeds in rice field (compression grass, eye vegetable, special-shaped sedge, barnyardgrass)

[0026] Test method: The test site is flat and the fertility is uniform. The pH value of the soil is about 6.8, and the organic matter content is about 17.5g / kg. The seeds were sown on June 10, and the rice seeds were soaked to accelerate germination. Transplanted on July 8 and managed according to conventional methods. The medicine soil method was used to apply pesticides 5 days before rice transplanting. A blank control treatment area was set up, repeated 3 times, and the plots were randomly arranged in blocks. Investigate the weeds in each plot 14 days after the application, and calculate the fresh weight control effect.

[0027] Test drug:

[0028] ① 25% propargyl oxadiazone dispersible oil suspension concentrate (commercially available)

[0029] ② 25% West grass wettab...

Abstract

The invention provides a weeding composition containing oxadiargyl and simetryne. The weight ratio of oxadiargyl to simetryne is (1:20)-(20:1). The weeding composition can be used for controlling weeds in paddy fields, can reduce the use amount of chemicals, reduces the harm to the environment, and inhibits the generation of drug resistance of weeds.

Description

technical field [0001] The invention belongs to the field of pesticides, in particular to a herbicidal composition containing propargyl oxadiazone and siquat. Background technique [0002] Proxadiazone is a new type of oxadiazole nitrogen-containing heterocyclic pre-emergence selective broad-spectrum herbicide, mainly used for pre-emergent control of various annual crops such as rice, sunflower, potato, sugar beet, vegetables, orchards, etc. Grass, Sedge and Broadleaf weeds. This product can control weeds such as barnyardgrass, Chenopodium, Amaranthus, Heliconia, Stephania, and Brachiaria. [0003] Xiqujing belongs to the triazine herbicides and is a selective pre-emergence soil treatment agent of systemic conduction type. It is suitable for the control of weeds such as barnyardgrass, cow hair grass, spinach, Alisma, Arthia sativa, Motherwort, Arthia sativa and other weeds in paddy fields. It can be used in combination with herbicides such as carbapan, butachlor, and Wodaz...
