Abstract
The invention relates to a herbicide prepared by the binary combination of pendimethalin and prometryn and a preparation method thereof. The herbicide comprises the following components in percentage by weight: 10-40 percent of pendimethalin, 5-30 percent of prometryn, 5-15 percent of synergistic agent, 8-20 percent of emulsifying agent and the balance of solvent. A preparation method of the herbicide comprises the following steps of: in a reaction kettle, according to the percentage by weight, mixing and stirring the pendimethalin and the solvent; mixing and stirring the prometryn and the solvent; mixing and stirring the two solutions; adding the emulsifying agent and the synergistic agent into the reaction kettle together to mix for 10-15 minutes; adding the balance of solvent to mix for 20-30 minutes; then, standing; filtering; filling; sampling; analyzing; and preparing a finished product. The herbicide is a high-efficiency broad-spectrum herbicide, is used for soil spray in a preemergence weed mass budding initial period before or after sowing economic crops of cotton, peanuts, an orchard, a mulberry field, a tea garden, tobaccos, and the like, can completely realize the no weed disease of crops in time of infertility when being applied 120-180g per mu, and the applying cost of the herbicide is 19.8-21.3 percent lower than the cost of the solely-applied pendimethalin or the solely-applied prometryn.

Embodiment 15
" hundred green bristlegrass are removed day wolf No. 12 " of the present invention weed killer herbicide application example
The weed killer herbicide that pendimethalin of the present invention and prometryn binary built are made (sample of embodiment 2), the a large amount of rudiment of weeds initial stage soil spraying before on cotton, peanut, orchard economic crops, broadcasting preceding or broadcast the back seedling in academy of agricultural sciences's farmland weed research department, Hubei Province's in March, 2010, carry out 50 square metres fritter test respectively, kill the effect of weeds and list in table 2 (three test mean values.Product in this Herbicidal composition scope all has identical effect).From table in the data as can be seen: the effect of " hundred green bristlegrass are removed day wolf No. 12 " management of weeds is more effective than single use pendimethalin and prometryn.This explanation " hundred green bristlegrass are removed day wolf No. 12 " of the present invention Herbicidal composition is scientific and reasonable, and the type selecting of QB-10 synergist in product structure played typical effect.
The weeds in field preventive effect was investigated in dispenser in 45 days before the back seedling was broadcast in table 2 cotton, peanut, orchard
The weed killer herbicide using method that pendimethalin of the present invention and prometryn binary built are made:
1. soil was sprayed before cotton was broadcast the back seedling, prevented and kill off annual gramineous weed mu 100-120g, converted water 60kg;
2. before peanut was broadcast preceding or broadcast the back seedling, annual gramineous weed mu 100-140g was prevented and kill off in weeds rudiment initial stage soil spraying, converts water 60kg;
3. the orchard is in weeds rudiment initial stage dispenser, and mu is used 120-180g, converts water 60kg, and a dispenser can reach effective control weed community harm.
