Description

A kind of bentazone complex weedicide and its application
Technical field
The invention belongs to technical field of pesticide, is related to a kind of complex weedicide containing bentazone, can be used for wheat paddock weeding.
Background technology
The plantation of Semen Tritici aestivi is with a long history, is only second to Oryza sativa L. in China's cultivated area and total output, is second largest cereal crops, Account for the 22% of total output of grain.Weeds of wheat mainly has broad leaved weed, dried tuber and grassy weed, wherein, in whole nation distribution It is more universal and heavier weeds of causing harm to wheat seedling have 19 kinds, including descurainia sophia (l.) webb ex prantl, Herba Galii Teneri, Herba Viviae Sativae, little Herba chenopodii, concave head amaranth, horse Bitterroot, Herba stellariae mediae, caput grass, Bermuda grass, Paspalum distichum, setaria glauca, Herba Cirsii, Herba Commelinae, Herba Polygoni Avicularis, Herba seu Flos Convolvuli arvensves, Herba Sonchi Arvensis, little rotation Flower, Thalaspi arvense L., Semen Euphorbiae, spire Semen Euphorbiae and phragmites communiss.Weeds of wheat is by fighting for moisture, nutrient, occupying ecology with Semen Tritici aestivi Space and survive the winter carrier and vector as some wheatland pest and disease damages etc. directly or indirectly affect Semen Tritici aestivi yield and Quality, wheatland crop smothering cause wheat yield rate about 30% every year.
With the development of agricultural cience and farming techniques, the own Jing of field application chemical herbicide becomes elimination farmland weed, defeats grass Waste important means, be for many years peasant always using and saving of labor, save time, laborsaving and efficient method.Wheat field herbicide Kind is increasing, and usable floor area is also increasing, and herbicide resistance is increasingly becoming the significant problem that farmland weed is prevented and kill off, And existing herbicide kind is difficult while preventing and kill off the broad leaved weed of wheat paddock, dried tuber and grassy weed, selection is suitably removed Careless agent compounding can not only expand weed control spectrum, increase preventive effect, delay Weed Resistance, and can reduce the consumption of medicament, reduce making With cost, the generation of poisoning is reduced.
Bentazone is selective contact killing type herbicide, for seedling stage cauline leaf process, is acted as by blade contact With, when using in wheat paddock, bentazone is transmitted to inhibited photosynthesis in chloroplast by blade face infiltration and makes weeds dead, Be mainly used in preventing and kill off Herba Galii Teneri, Herba Capsellae, field thistle, Herba Xanthii, Rhizoma Cyperi, ferrum garden dish, multitude, thorn garden, Zhi Yuan, hold back blue dish, Thalictrum aquilegifolium L. var. sibiricum Regel, Broad leaved weed and the dried tubers such as Dens Equi is looked for, mexicana, Herba potamogetonis distincti, but it is invalid to grassy weed.
Pyroxsulam, chlortoluron, grand chlorine sulphur, isoproturon, metsulfuron-methyl, iodosulfuron-methyl-sodium can be prevented used in wheat paddock Except most of annual gramineous weed and part broad leaved weed, and mesosulfuron, alkynes oxalic acid, pinoxaden can prevent and kill off Semen Tritici aestivi Tanaka major part grassy weed, but to broad leaved weed almost without effect.
Each of the above herbicide has oneself distinctive herbicidal spectrum and the weeds that can not be prevented and kill off, and herbicidal spectrum is single, single Solely using the generation that can not completely effectively control weeds of wheat, this is accomplished by improving prevention effect by compounding.
The content of the invention
The technical problem to be solved has been to provide a kind of complex weedicide containing bentazone and its application, should Complex weedicide has extensive weed control spectrum, can prevent and kill off broad leaved weed, dried tuber and the grassy weed of wheat paddock simultaneously, play Good synergism, with obvious potentiation, herbicide speed is fast, and can delay Weed Resistance, to Semen Tritici aestivi and after Stubble crop has good safety.

Field control effectiveness test
Reagent agent：8 kinds of bentazone complex weedicides of embodiment 1～8.
Comparison medicament：25% bentazone water preparation (commercially available).
For studying thing：Semen Tritici aestivi, Caulis et Folium Tritici aestivi were 2～5 leaf phases, were grown fine, robust plant, without other pest and disease damages.
Prevent and kill off object：Broad leaved weed, dried tuber and grassy weed.
Test method：Test totally 8 process, each processes three repetitions, cell random alignment, plot area 100m2.Enter Stem and leaf spraying of row, and the synoptic data on the dispenser same day and its one week after is recorded, after medicine, 30d observes the preventive effect of each medicament, tool Body is as follows：According to the area of experimental plot, the good various medicaments of precise, and after being watered dilution, using knapsack sprayer, enter Row even spraying, the special Fan spray head of sprinkler selection herbicide.During spraying, it should be noted that medicinal liquid is uniformly sprayed application to experimental plot In, accomplish there is no drain spray, the phenomenon of many sprays.A blank district, not dispenser are set separately.
The dispenser same day and its one week after it is fine, temperature between 10 DEG C -25 DEG C, 30d observations weeds after administration Death condition, and the herbicidal effect of the various medicaments of comparison, the method for testing of preventive effect are as follows：Take at random at 4 points per cell, per investigation 1/4 square metre, before dispenser, after dispenser, 30 days record weeds strain numbers, calculate weeds strain preventive effect.Additionally, will also 1 after medicine～ In 30d, the growing state of observation crop, is compared with blank district, to investigate whether medicament has poisoning to crop.
