Abstract
A synergistic herbicidal composition which comprises as active ingredient in a total amount of 1-90 % by weight a 1:4-2.3:1 mixture of N-(2'-ethyl-6'-methyl-phenyl)-N-ethoxymethyl-2-chloro-acetamide and 2-nitro-1-(4- nitro-phenoxy)-4-trifluoromethyl benzene, in admixture with usual inert solid or liquid carriers and auxiliary agents, is particularly useful for selectively combating Panicum miliaceum in maize cultures.
Description
SPECIFICATION
Synergistic herbicidal composition
This invention relates to a synergistic herbicidal composition, a processforthe preparation thereof and the use ofthe said composition in agriculture for combating weeds.
The present invention is based on the recognition that N - (2' - ethyl ethyl - 6'- methyl - phenyl) - N - ethoxymethyl - 2 - chloro - acetamide (ACETOCHLOR) and 2 - nitro -1 -(4- nitro -phenoxy)-4- trifluoromethyl - benzene (FLUORODIPHEN) exhibit synergistic effect.
The active ingredient components ofthesynergis- tic herbicidal composition ofthe present invention are known per se. Thus the preparation of ACETOCH
LOR is described in US patent No. 3,442,945 and that of FLUORODIPHEN is disclosed in British patent No.
1,033,163.
Hitherto herbicidal compositions comprising chloro amino triazine derivatives were most widespreadly used for combating weeds occurring in maize cultures. The disadvantage ofthe said herbicidal compositions is that they are inactive against certain monocotyledonous weeds, since the said weeds, similarly to maize, are capable of detoxicating the herbicidal active ingredients/See K.I.N. Jensen;
G.R. Stephensen and L.A. Hunt: "Detoxification of atrazin in three Gramineae subfamilies" (Weed Sci.)
Champaign, III., 1977., Vol. 25, pages 212-220.1.
It is known that second to maize it is Panicum miliaceum which is most capable of detoxicating the herbicide atrazin and this is the reason why the said weed strain is so widespread. Other herbicides generally used in maize cultures (thiourea and urea derivatives, acetanilides, etc.) are not sufficiently effective against Panicum iliaceum either.
Several effortswere madeto combate the above dangerous weed species and various compositions and biological procedures were elaborated. Encouraging results were however obtained only by post-emergent treatment.
It is the object of the present invention to provide a herbicidal composition and method suitable for effectively combating Panicum miliaceum weed species.
It has been found in a surprising mannerthat combinations comprising Acetochlor and Fluorodiphen in certain ratios exhibit a herbicidal effect which is superiorto the sum of the effect ofthe components used per se i.e. the compositions of the present invention possess synergistic properties.
According to the present invention there are provided herbicidal composition comprising as active ingredient in a total amount of 1-90 % by weight a 1:4-2.3:1 mixture of N - (2' - ethyl -6' - methyl - phenyi) - N - ethoxymethyl - 2 - chloro - acetamide and 2 - nitro -1 -(4- nitro- phenoxy} - 4 - trifl uoro - methyl benzene in admixture with usual inert solid or liquid carriers and auxiliary agents.
The liquid carrier may be an aliphatic and/or aromatic hydrocarbon, alcohol, ketone, ester, prefer ablyxylene orcyclohexanone. The solid carrier may be any suitable natural mineral, preferably silicic acid, China-clay, caolin, ground limestone and/or a synthetic silicate.
The compositions of the present invention may comprise suitable wetting and/or dispersing agents, non-ionic and/or anionic surfactants, lignine sulfonic acid derivatives, adhesives or the selectivity improving agents, etc.
The compositions ofthe present invention may be finished in any suitable form applicable in agriculture or horticulture e.g. in the form of in water emulsifiable concentrate, wettable powder, dusting powder, granule, etc.
The emulsifiable concentrate and wettable powder may be diluted with water to provide a ready-use spray, while the granules may be directly applied onto the soil and used in a pre-emergent manner. The optimal dose amounts to about 1 kg of total active ingredient/ha under culturing vessel conditions.
The compositions according to the present invention can be preferably used for combating monocotyledonous weeds without damaging the cultivated plants. The compositions are particularly useful due to their selective activity in maize cultures against panicum miliaceum.
The activity tests are carried out by usual and well-known methods/L. Bånki: "Bioassay of pesticides in the laboratory", Akadbmiai Kid6, Budapest, 1978, pages 292-302; J.G. Horsfall (1945), "Fungicides and their action", Walthem, Mass USA Chronica Botanica; Scandari (1962): "Sinergismo di efficacia anticritlogamica tra Maneb e zolfo o polisolfuro di bario o Thiram", Notiz Malatt, Plante 61,3-35,37-48, 53-69/. These methods are particularly suitable for the determinations of the simultaneous-- i.e. synergistic, additive or antagonistic -- effect of two bioactive compounds.
In Figure 1 the following activity data of ACETOCH
LOR (A) and FLUORODIPHEN (F) against Panicum miliaceum are shown: measured activity of the components when used perse; - expected effect (on the basis ofthe per se measured data);
- measured activity of the combination of the two compo ents.
It appears from Figure 1 that at the preferable active ingredient ratio the measured activity of the combination is by more than 30 % higher than the expected value and this clearly proves the synergistic surpluseffect.
The unforeseen and surprising advantage ofthe synergistic composition of the present invention resides in the factthat it enables a highly efficient and safe pre-emergent protection against Panicum miliaceum in maize culture by using a relatively small
pesticidal dose whereby the cultivated plant is nor damaged even to the slightest extent.
Further details ofthe composition ofthe present
invention and the biological activity thereof are shown in the following non-limiting Examples with
out limiting the scope of protection to the said
Examples.
Example 1 Glasshousetests in a cultivating pot
9 kg of a 1:1 mixture of field soil and sand soil are placed in cultivating pots (30 x 30 x 30 cm), whereupon 100 MVSC 1295 (FAO 200) maize hybrides and 100 Panicum miliaceum weed-seeds a re sown into each pot in a depth of 4 cm and 2 cm, respectively. The surface of the soil is treated with an emulsion spray prepared by dilating with water an emulsifiable concentrate (EC) having the composition disclosed in Table 1 and containing 50 % by weight of the active ingredient. The doses and results of the activity test are summarized in Tables 2-4.
Plants nottreated with thetestcompositions serve as control. During the test the temperature of the glass house is maintained at 15-25 C, the strength of illumination amounts to 24 klux, the intensity is 70
W.m-2 and the relative humidity content amounts to 80%.
The results are evaluated 15 days after shooting.
The state and condition of the plants is expressed with the aid ofthefollowing bonityscale: 0 = no damages;
1 = not more than 25 % of the leaves are damaged;
2 = the distortion (deformation) ofthe leaves and the growth inhibition is not largerthan 50 %; 3 = the distortion (deformation) of the leaves and the growth inhibition is not higherthan 75 %; 4 = complete, 100 % death of the leaves.

active ingredient ratio limits of from 1 :4to 2.3:1.Best
results are obtained atan active ingredient ratio of 1:2 -1:1.
Example 2
Field tests
Thetests are carried out on plots having a plot-size of 250 m2, in soil having an organic substance content of 2.44 % and in four replicates. Inthethoroughly homogenized soil at the beginning of May 800,000 seeds/h a of maize/Pioneer 3978/are shown at a depth of 5-6 cm.The day following the sowing the plots are treated separately with an aqueous suspension spray prepared from the 80 % by weight wettable powder
(WP) having the composition according to Table 5 and with 4 % by weight granule(G).Sprayingis carried out by using a Haflinger spraying machine and the granules are spread with the aid of a Fontane granule spreading apparatus. Untreated plants serve
as control.The test is evaluated at the beginning of
October by counting the panicum miliaceum panicles
on an area of 4 x 1 m2 on each parcel and visually evaluating the symptoms of damages on maize.
The results are summarized in Table 6.

The data of Table 6 show that plots treated with a dose of 4.2 kg of active ingredient/ha of the synergistic combination were substantially free of Panicum miliaceum during the complete cultivating period i.e. the dangerous weed was practically completely eliminated. On the other hand treatment carried out
by using the said active ingredients separately was
completely ineffective. Ifthe components are applied verse in double doses (i.e 100 % excess) the
Panicum miliaceum is not effectively combated moreover certain damages of maize are observed.
Differentformulations ofvarying concentrations (WP and G) proved to be equivalentfrom the pointofview of biological activity.
