Problems solved by technology
[0003] Although the use of glyphosate has played an important role in ensuring safe agricultural production, farmers in my country generally lack the knowledge of scientific use of herbicides and are accustomed to large doses, repeated and single use of pesticides to control weeds. Target weed quickly becomes resistant to glyphosate

Embodiment 1
[0032] 1. Materials and methods
[0033] 1. Materials: There are 5 kinds of weeds in the test, namely broad-leaved weeds Nightshade and Abutilon, grass weeds Goosegrass, barnyardgrass and crabgrass; the glyphosate used is Roundup, It contains 41% glyphosate isopropylamine salt, produced by Monsanto Company of the United States; spray equipment: Singapore Linong HD400 knapsack manual sprayer, produced by Singapore Linong Pte Ltd.
[0034] 2. Method: 16 treatments were set up in the test, and the doses of 41% glyphosate isopropylamine saline solution were 100ml / mu, 150ml / mu and 200ml / mu, namely 41g a.i. / mu, 61.5g a.i. / mu and 82g a.i. per mu; the dosage of biogas slurry concentrate is 150ml / mu, 300ml / mu, 600ml / mu and 1200ml / mu respectively; the water consumption per mu is 30L, after the three are mixed (see Table 1 for details), spray evenly on the On weed seedlings.

The invention specifically discloses application of concentrated biogas slurry as a synergist for glyphosate isopropylammonium, belonging to the field of pesticides. Specifically, glyphosate isopropylammonium and concentrated biogas slurry are mixed and diluted and are then sprayed on stem leaves for treatment of weeds; after dilution, the concentration of glyphosate isopropylammonium is 1.37-2.73 * 10<3> g a.i. / ml while the concentration of concentrated biogas slurry is 0.5 to 4% (v / v); and the usage amount of glyphosate isopropylammonium is 41 to 82 g a.i. / mu while the usage amount of concentrated biogas slurry is 150 to 1200 ml / mu. According to the invention, concentrated biogas slurry and glyphosate isopropylammonium are mixed according to a certain ratio and used; concentrated biogas slurry has obvious synergistic effect on glyphosate isopropylammonium; and in virtue of concentrated biogas slurry, the usage amount of glyphosate isopropylammonium is substantially reduced by 25 to 50%, weeding effect is generated 3 to 5 days earlier, a controllable weed growth period is postponed to a four-to-five-leaf period, and weeding speed and control effect are effectively improved.
Description
technical field [0001] The invention relates to the field of pesticides, in particular to the application of biogas slurry concentrate as a synergist of glyphosate isopropylamine salt. Background technique [0002] Glyphosate is a broad-spectrum killing and conductive organophosphorus herbicide developed by Monsanto Company of the United States. As one of the best-selling pesticides in the world, it has been used in most orchards, cotton fields and wastelands in southern my country since the mid-1980s , achieved a good effect. In recent years, with the intensive management of agricultural production and the improvement of crop multiple cropping index, the area of no-tillage and low-tillage crop fields in my country has been continuously expanded, and the technical level of farmers' targeted protection and pesticides has been continuously improved. In addition, there is still a lack of other effective post-emergence stem and leaf Treatment of herbicides to control broad-leav...
