The invention adopts an additive solid carrier, a wetting agent and a dispersing agent, etc. commonly used in the pesticide field and can be made into compound herbicide in the form of wettable powder, water dispersible granule, dry suspension and oil suspension, etc. The invention has the advantages that the herbicide has significant synergistic action and can effectively prevent and remove the main gramineae weed and broad-leaved weed, etc. in corn field, meanwhile, total control effect is improved by 4.3-35.9 percent and control rate of the main broad-leaved weed in corn field is up to 100 percent in particular; safety on crop is improved and yield increase of the corn is up to 15 percent; the terbuthylazine which has smaller phytotoxicity on succeeding crop is adopted as compound agent and then phytotoxicity is reduced; control cost is reduced by 22.2 percent.
Description
Technical field
The invention belongs to pesticide field, relate in particular to a kind of corn field herbicide, more particularly, it relates to the composite corn field herbicide of a kind of nicosulfuron Garagard.
Background technology
At present in corn field herbicide, rimsulfuron 25 (has another name called rimsulfuron in the sulfonylureas commonly used, treasured becomes) and the nicosulfuron controlling weeds, rimsulfuron 25 and nicosulfuron are mainly used in prevents and kill off barnyard grass grass in the corn field, eleusine indica, lady's-grass, grassy weed and kitchen gardens such as green foxtail, Amaranthus retroflexus, the iron amaranth, broad leaved weed and sedge weeds such as knotweed, but because of it is to be the weeding principle with interior suction conduction, so the action period is long, it is slow to take effect, not good to the weeds removal effect, and the sulfonylurea herbicide selectivity is strong, sensitivity differences to Different Crop is bigger, therefore cause that easily poisoning causes crop production reduction, use cost is higher separately on producing.In order to overcome these shortcomings, people mix use with sulfonylurea herbicide with other weed killer herbicide, most and the composite formation compound herbicide of atrazine (atrazine ATRAZINE) in corn field herbicide, it is a kind of with rimsulfuron 25 and the composite compound herbicide of atrazine (atrazine ATRAZINE) to be 98102398.3 patent disclosures as application number, 01127499 and 200510095625 patent disclosure a kind of nicosulfuron and composite herbicide specially for corn field of atrazine of utilizing, application number a kind of chlortoluron that utilizes that has been 200510082977 patent disclosure, the corn field herbicide that atrazine and nicosulfuron are composite.Production practices prove, by the composite preventive effect that improved to a certain extent, reduced cost, but preventive effect is still undesirable, and atrazine longevity of residure in soil is longer, easily injure succession crop as the residual quantity of dosage Gao Shiqi in soil, cause the underproduction in various degree, this medicine is disabled in European Union.And rimsulfuron 25 has only and adopts directed spraying in the ranks, if the improper crop of using method is easy to generate poisoning, and to the control efficiency of weeds not as good as nicosulfuron.

The former medicine of (1) 97% Garagard (Shandong Binnong Technology Co., Ltd.)
The former medicine of (2) 95.3% nicosulfuron (pesticide chemical Co., Ltd of Jiization group) is according to pre-test result, and the consumption of nicosulfuron and Garagard sees Table 1 respectively
3, test method
Adopt pot-culture method, selecting diameter for use is the basin alms bowl of 20cm, test soil quantitatively is filled to 4/5 place of basin alms bowl, adopt basin alms bowl bottom infiltrating irrigation mode, make soil moistening fully, supply the uniform broadcasting of examination weed seed in soil surface with pretreated, 50 weed seeds of every basin alms bowl, earthing 0.8cm places in the greenhouse and cultivates then.Condition of culture is: 15～20 ℃/25～30 ℃ of temperature (N/D), and illumination 0/8000～10000Lx (N/D), light application time 12h/12h (N/D), relative moisture is 70% ± 10%.Treat that the weeds laggard seedling in the ranks of emerging decides strain, every basin alms bowl is 10 strains, treats that weeds grow to 5 leaves and adopt ASS-1 type pesticide spraying system (XR8003 shower nozzle, atomisation pressure 0.3MPa, spouting liquid 400kg/hm2) spray medicine, the fresh weight preventive effect of the various weeds of two all " Invest, Then Investigate "s during the phase.More than test all repeats 3 times, and each the processing repeated 4 basins.Condition of culture is the same.Measurement result sees Table 1.
Adopt equivalent collimation method to measure nicosulfuron and the best proportioning of Garagard.Obtain the effective dose ED90 that two single agent and each mixture suppress barnyard grass grass fresh weight growth 90% by the linear regression of concentration logarithm-inhibiting rate probit value, simulate ED90 isoeffect curve figure with calculator.(Additive Dose Model ADM) estimates the synergy of using with between each medicament to adopt the dosage additive model.
In the equivalent line chart that draws, the degree size that actual observed value departs from the ADM predicted value can reflect the enhancing of the drug effect that is produced when mixture uses separately with respect to single agent or weaken, and this degree is represented with synergy index K.As shown in Figure 1,
When K＜1, the expression antagonism; When K=1, the expression summation action; As K〉1 the time, expression synergistic effect, synergy multiple=K-1.Adopt equivalent collimation method to carry out indoor joint toxicity measuring as can be seen, the composite ED90 equivalent line of nicosulfuron and Garagard is under the additive effect line, therefore illustrating that both use with adopts the cauline leaf facture to prevent and kill off the barnyard grass grass notable synergistic effect is arranged, and nicosulfuron and Garagard are to the synergy index of barnyard grass grass
Maximum synergy multiple=K-l=1.27-1=0.27, and the composite mixture of nicosulfuron and Garagard reaches at 90% o'clock to the careless fresh weight inhibiting rate of barnyard grass, and both ratios are 1: synergistic effect maximum during 15-20.
The different proportionings with Garagard of table 1 nicosulfuron are to the inhibition effect of barnyard grass grass
