Problems solved by technology

The following types of weeds are common in paddy fields in my country: paddy field weeds, grasses, broad-leaved and sedges, such as barnyardgrass, commelina, dwarf sage, squid, cattle felt, etc., due to long-term use of chemical Pesticide control has caused weeds to have varying degrees of resistance to a variety of chemical herbicides, and the control effect has dropped significantly, making farmers have to increase the amount of pesticides to improve the control effect, but it also reduces the safety of agricultural products

Embodiment 1

[0036] Determination of the herbicidal soil treatment activity of bispyrazole compounds:

[0037] 1. Test drug: Take bispyrazole compounds HP-10-1~HP-10-6 as original drugs.

[0038] 2. Test weeds: zinnia (Zinnia lelgans Jacq.); chrysanthemum (Abutilon theophrasti Medic.); golden foxtail (Setaria golrca (L.) Beauv); barnyardgrass (Echinochloa crus-galli (L.) Beauv) .

[0039] 3. Test method: Sow quantitative seeds of gramineous weeds (barnyardgrass, golden foxtail) and broad-leaved weeds (zinnia, chrysanthemum) in paper cups with a diameter of 7 cm filled with nutrient soil. Cover the soil with 1cm, and cultivate it in the greenhouse according to the conventional method after pressing and watering. Gramineae weeds grow to 2-leaf stage, and broad-leaf weeds 2-leaf stage are treated with post-emergence stem and leaf spraying, and pre-emergence soil spraying treatment is carried out 24 hours after sowing. According to the experimental design dose (150, 600g.a.i / hm 2 ), the sp...

Abstract

The invention provides a weeding composition containing bipyrazolate compounds, and applications thereof. The chemical structure of the bipyrazolate compounds is disclosed in the invention, and the numbers are HP-10-1 to HP-10-6. The invention also discloses applications of the bipyrazolate compounds in preparation of agricultural herbicides as active components. The weeding composition can be used for preventing and killing rice field weed, grassy weed, broadleaf weed, and sedge weed such as barnyard grass, dayflower, Sagittaria pygmaea, pondweed, and Eleocharis yokoscensis. The beneficial effects are that: the weeding spectrum is wide; weeding time is short; the effect lasting period is long; a synthesis method is simple; cost is low; and combination effect is excellent.

Description

technical field [0001] The invention relates to the field of agricultural technology, in particular to a herbicide combination containing bispyrazole compounds and its application. Background technique [0002] Crop weed disease is one of the main agricultural disasters in rice fields in my country. It has the characteristics of various types, great impact, and eradication. Its occurrence range and severity often cause great losses to my country's national economy, especially agricultural production. The following types of weeds are common in paddy fields in my country: paddy field weeds, grasses, broad-leaved and sedges, such as barnyardgrass, commelina, dwarf sage, squid, cattle felt, etc., due to long-term use of chemical Pesticide control has caused weeds to produce varying degrees of resistance to a variety of chemical herbicides, and the control effect has dropped significantly. Farmers have to increase the amount of pesticides to improve the control effect, but it also...
