Wheat field weeding is the most important management measure at the wheat seedling stage, is to ensure the normal growth and development of wheat premise and guarantee, wheat field weeds are many types, serious harm. Broad-leaved weeds, in particular, are more harmful. Today I will introduce to you a herbicide formula that specializes in killing broad-leaved weeds in wheat fields, which has a good anti-removal effect on large grasses and small grasses, and can be formulated by yourself.
Broad-leaved weed common in wheat fields
Broadleaf weeds in wheat fields are the most widespread, most diverse and most harmful weeds in wheat fields. Common broad-leaved weeds are artemisia, cabbage, pig plague, lacquer, cattle wisps, wisps, big nest vegetables, maijiagong and other more than 10 kinds, these weeds are cold and drought-tolerant, fast reproduction, and wheat competition for water and fertilizer space, or a variety of diseases and insect pests of wintering place, timely prevention of these weeds, in order to make wheat seedlings normal growth and development.
Introduction to the recipe
At present, there are many varieties of herbicides for the control of broad-leaved weeds in wheat fields, and practice has shown that due to years of use, the resistance of weeds has increased, and the weeding effect of a single herbicide is getting worse and worse. Mixing herbicide varieties with different mechanisms of action is the simplest, most effective and lowest cost method to overcome drug resistance and improve efficacy. After several years of experiments, the three herbicides of benzosulfuron, azasandone and 2-methyl-4 chloro sodium salt are mixed, which have the dual effects of touch killing and internal suction conduction, which can completely kill the aboveground and underground parts of weeds, and the weeding is cleaner and more thorough. It has a good killing effect on a variety of broad-leaved weeds such as pig plague, multiplicity, large nest vegetables, wild rapeseed, artemisia seed, cabbage, and lacquer. Weeding is fast and dead grass is thorough.
Besulfuron is a sulfonylurea herbicide, with good systemic conductivity, can be absorbed by the roots and leaves of weeds, and conducted in the plant, the roots, stems and leaves of weeds have a good killing effect, due to years of use, weeds have produced a strong resistance to drugs.
Zoxazone is a triazolidone herbicide, mainly to touch killing, no systemic, after spraying, 3-4 hours after the weeds appear poisoning symptoms, 2-4 days of weeds can die, fast action, fast effect and other characteristics, however, not easy to die roots, especially older weeds are prone to recurrence.
2-methyl-4 chloride sodium is a hormonal herbicide, with good systemic conductivity, after spraying, can be absorbed by the rhizomes and leaves of weeds, by destroying the transfusion tissue of dicotyledonous plants, the growth and development of weeds are disturbed, resulting in twisted stems and leaves, and the base of the stem expands and becomes thicker or cracked. Dead grass is thorough and not easy to recur, but the speed of action is slow.
The three different mechanisms of action of the herbicide mixed use, effectively overcome the deficiencies of each single agent, the synergistic effect is very significant, not only has a good systemic conductivity, but also has a good touch killing, after spraying, the stems and roots of weeds have a good killing effect, with clean weeding, good quick-acting, long shelf life, cheap price and other advantages, is the ideal formula for the control of broad-leaved weeds. At present, the formula has a number of registered production manufacturers.
How to use
In the wheat 4 to 7 leaf stage, broad-leaved weed 2 to 4 leaf stage, 50 grams of 55% benzozole·2 methyl sodium wettable powder per mu, mixed with water 20 to 30 kg evenly sprayed, the wheat field common sowing of artemisia, cabbage, pig plague, paint, wisps, big nest vegetables and other broad-leaved weeds have a good anti-removal effect. Weeding is clean and thorough, and weeds do not rebound.
