Description

Herbicide for peanut field
Technical Field
The herbicide is applied in the 3-4 leaf period of peanuts and the 2-4 leaf period of weeds, has obvious compounding and synergism, improves the weed control effect of the peanut field, and improves the safety and the yield of the peanuts.
Background
The main weeds in the peanut field are grassy weeds such as barnyard grass, goosegrass herb, crab grass and green bristlegrass and broadleaf weeds such as purslane, redroot amaranth and acalypha australis, and soil treatment agents are mainly adopted for preventing and killing in the past. However, the soil treatment agent has high requirement on soil humidity, peanuts are generally sown in the last ten days of May in North China, and at the moment, the straight north is dry and rainless, so that the pesticide effect of the peanut soil treatment agent is reduced, the lasting period is short, and meanwhile, the pesticide has certain phytotoxicity on peanut seedlings, the peanut seedlings are shown to be deformed by leaves, and the growth of plants is inhibited.
Compared with a soil treatment agent, the stem leaf treatment agent has the advantages of small environmental pollution, small dosage, low requirement on soil humidity and the like, becomes a herbicide type which is mainly popularized in the current production, and the stem leaf treatment agent tends to replace the soil treatment agent at foreign countries.
The stem and leaf treating agent used in peanut field mainly comprises haloxyfop-methyl, quizalofop-p-ethyl, fomesafen, imazapyr, lactofen, fenoxaprop-p-ethyl, fluoroglycofen-ethyl and the like, but when the herbicide is used alone, only gramineous weeds or broadleaf weeds can be controlled, and 2 types of weeds cannot be controlled simultaneously. In order to effectively control the gramineous weeds and the broadleaf weeds in the peanut fields at the same time, a herbicide for controlling the broadleaf weeds and a herbicide for controlling the gramineous weeds are compounded, so that the weed control spectrum can be effectively expanded. The stem and leaf compound preparation used in peanut field mainly comprises quizalofop-p-ethyl fluoroglycofen emulsifiable concentrate, quizalofop-p-ethyl fluorosulfan emulsifiable concentrate, quizalofop-p-ethyl lactofen emulsifiable concentrate and the like. The field efficacy test shows that fluoroglycofen-ethyl is easy to cause phytotoxicity to the peanuts; meanwhile, with the increase of the service life, resistant weeds such as large crabgrass, goosegrass and barnyard grass which generate resistance to the herbicide appear, so that the control effect is obviously reduced. Under such circumstances, the development of a herbicide variety for foliage which effectively controls grassy and broad-leaved weeds in peanut fields and simultaneously effectively controls resistant weeds will become one of the main tasks of future pesticide preparation workers.

The culture conditions were: the temperature is 28-32 ℃/25-28 ℃ (N/D), the illumination is 0/8000-10000 Lx (N/D), the illumination time is 14h/10h (N/D), and the relative humidity is 70% +/-10%. Thinning and fixing the seedlings after the weeds grow out, wherein 10 seedlings are planted in each pot, and an ASS-1 type pesticide spraying system (XR8003 nozzle, spraying pressure of 0.3MPa and spraying liquid amount of 400 kg/hm) is adopted when the weeds grow to the 5-leaf stage2) And (4) spraying the pesticide. The above experiments were repeated 3 times, 4 pots for each treatment. The culture conditions were as above.
After 2 weeks of application, investigating the fresh weight of the overground part of the weeds (shearing off the overground part of the weeds, weighing the overground part of the weeds respectively), calculating the growth inhibition rate of the fresh weight of each treatment according to a formula (1), and calculating the growth rate according to a formula (2);
