(57) A bstraet: Novel active agent combinations, comprising extracts of the seeds of the neem tree and Dctive agents of groups (B) to (F), as specified in the description, possess very good insecticidal and acaricidal properties.

Active compound combinations

The  present  invention  relates  to  novel  active  compound  combinations  which

comprise, firstly, known extracts from seeds of the neem tree and, secondly, further

known pesticidally active compounds, and which have very good insecticidal and

acaricidal properties.

It is already known that extracts from the seeds of the neem tree have insecticidal

10    properties (cf. "Rtirnpp Chemie Lexikon", 9th edition, page 2954, Georg Thieme Verlag, Stuttgart-New York, 1991). The activity of this substance is good; however, it is sometimes unsatisfactory at low application rates.

It  is  furthennore  kno\\'11  that numerous pyrethroids,  carbamates,  phosphoric  acid

15    ~erivatives and heterocycles can be used for controlling animal pests such as insects

and undesirable acarids (cf. WO 93-10 083; DE-A 2 717 040; Farm Chemicals Handbook 1998, C 328; EP-A 0 161 019 and EP-A 0 049 977). However, the activity
of these substances is likewise not always satisfactory at low application rates.

20    It has now been found that the novel active compound combinations comprising

A)    extracts from seeds of the neem tree

and

25

B)    an active compound from the group of the pyrethroids, consisting of

(1)    cypermethrin,

(2)    de1tamethrin,

30    (3) permethrin,

(4)    natural pyrethrum,
 
(5)    fenpropathrin,

(6)    cyfluthrin,

(7)    beta-cyfluthrin and

(8)    Jambda-cyhalothrin,

or

C)    an active compound from the group of the carbamates, consisting of

10    (9)    butocarboxim,

(10)    pirimicarb,

(!I)    propoxur and

(12)    methiocarb,

15    or

D)    a phosphoric acid derivative from the group consisting of

(13)    isazophos and

20    (14)    dimethoate,

(E)    an active compound from the group of the nicotiny!s or neonicotinyls consisting of

25    (15) imidacloprid,

(16)    thiacloprid,

(17)    thiamethoxam,

(18)    acetamiprid and

(19)    clothianidin,

30

or

(F)    an active compound from the group consisting of

(20)    abamectin,

(21)    diflubenzuron,

(22)    buprofezin,

(23)    triflurnuron,

(24)    diafenthiuron,

(25)    fipronil,

(26)    spinosad,

10    (27)    pymetrozine,

(28)    cyromazine,

(29)    dicyclanil,

(30)    bifenazate,

(31)    hexathiazox,

15    (32)    tebufenpyrad,

(33)    pyridaben,

(34)    the keto enol derivative (I) of the name 3-(2,4-dichlorophenyl)-4-(1,1-dimethyl-propyl-carbonyloxy)-5-spiro-<:yclohexyl-3-dihydrofiuan-2-one

20

and

(35)    the keto enol derivative (II) of the name 3-(2,4,6-trimethylphenyl)-4-(2,2-dhnethyl-propyl-carbonyloxy)-5-spiro-cyclopentyl-3-

25    dihydrofiuan-2-one

have very good insecticidal and acaricidal properties.

Surprisingly, the insecticidal and acaricidal activity of the active compound 30 combinations according to the invention is considerably higher than the sum of the

activities  of  the  individual  active  compounds.  Thus,  an  unforeseeable,  true

synergistic effect is present, and not just an addition of aetivities.

In the present case, extracts from seeds of the neem tree are to be understood as meaning all customary products which can be isolated from seeds of the neem tree by extraction or squeezing and which conta~ substantial quantities of azadirachtin.
These products include azadirachtin itself

Various extracts of seeds of the neem tree and azadirachtin itself are already lmown

10    (cf. 11 The Pesticide Manual11 11th edition, British Crop Protection Council 1997, No. 36 and also 11 R0mpp Chemie Lexikon11 , 91h edition, page 2954, Georg Thieme Verlag, Stuttgart-New York, 1991).

The insecticidally and acaricidally active components which are present in the active

15    compound combinations according to the invention in addition to the extracts from the seeds of the neem tree are likewise lmown. The following substances are specifically described in 11 The Pesticide Manua1'1, 111h edition, British Crop

In addition to  the extract from  the seeds of the neem tree, the active compound

30    combinations  according  to  the  invention  comprise  at  least  one  of  the  active

compounds  from  groups  (B)  to  (F).  Additionally,  they  may  comprise  further

insecticidally and/or acaricidally active components.

The synergistic effect is particularly pronounced if the active compounds are present in the active compound combinations according to the invention in certain weight ratios. However, the weight ratios of the active compounds in the active compound combinations can be varied within a relatively wide range. In general,

from 0.02 to 20 parts by weight, preferably from 0.3 to 17 parts by weight, of active

10    compound from group (B),

from 1 to 80 parts by weight, preferably from 1.5 to 70 parts by weight, of active compound from group (C),

and Eriophyes spp.

25

The fact that the active compound combinations are well tolerated by plants at the concentrations required for controlling insects and acarids pennits the treatment of above-ground parts of plants, of propagation stock and seeds, and of the soil. The active compound combinations according to the invention can be used for foliar
30    application or else as seed dressing.

The active compound combinations according to the invention are usually employed in the fonn of compositions (fom1Ulations), for the preparation of which it is possible to use

the extracts from the seeds of the neem tree in a commercia] preparation or in the form of isolated substances and

the active compounds of groups (B) to (F) either as such or in commercial

preparations.

10

The active compound combinations according to the invention can be conve~ed into

the    customary   compositions   (fonnulations),   such   as   solutions,   emulsions,

suspensions,  powders,  foams,  pastes,  granules,  aerosols,  rnicroencapsulatio?-s  in

poJyrneric compounds and in coating compositions for seeds, and UL V formulations.

15

These fonnulatians are produced in a known manner, for example by mixing the active compounds or active compund combinations with extenders, that is liquid solvents, Jique.fied gases under pressure, and/or solid carriers3 optionally with the use of surfactants, that is emulsifiers and/or dispersants, and/or foam farmers. If the

20    extender used is water, it is also possible to use, for example, organic solvents as auxiliary solvents. Essentially, suitable liquid solvents include aromatics, such as xylene, toluene or alkylnaphthalenes, chlorinated aromatics or chlorinated aliphatic

hydrocarbons,  such  as  chlorobenzenes,  chloroethylenes  or  methylene  chloride,

aliphatic hydrocarbons, such as  cyclohexane, or paraffins,  for  example petroleum

25    fractions, alcohols, such as butanol or glycol and also their ethers and esters, ketones, such as acetone, methyl ethyl ketone, methyl isobutyl ketone or cyclobexanone, strongly polar solvents, such as dimethylformamide and dimethyl sulpl10xide, and also water. Liquefied gaseous extenders or carriers refer to those liquids which are gaseous at normal temperature and under atmospheric pressure, for example aerosol

30    propellants, such as butane, propane, nitrogen and carbon dioxide. Suitable solid carriers are: for example ground natural minerals, such as kaolins, clays) talc, chalk,

quartz,  attapuJgite,  montmorillonite  or diatomaceous  earth,  and  ground  synthetic

minerals, such as finely divided silica, alumina and silicates. Suitable solid carriers for granules are: for example crushed and fractionated natural rocks, such as calcite, marble, pumice, sepiolite and dolomite, or else synthetic granules of inorganic and

organic meals, and granules of organic materials such as sawdust, coconut sheHs, maize cobs and tobacco stalks. Suitable emulsifiers and/or foam formers are: for

example nonionic and anionic emulsifiers, such as polyoxyethylene fatty acid esters,

polyoxyethylene  fatty  alcohol  ethers,  for  example  alkylaryl  polyglycol  ethers,

al1:ylsulphonates,  al1:yl  sulphates,  arylsulphonates,  or  else  protein  hydrolysates.

10    Suitable dispersants are: for example ligna sulphite waste liquors and methyl cellulose.

Tackifiers, such as carboxymethyicellulose and natural and synthetic polymers, in the fonn of powders, granules or latices, such as gum arabic, polyvinyl alcohol and

15    polyvinyl acetate, or else ,natural phospholipids, such as cepbalins and lecithins and synthetic phospholipids, can be used in the fonnulations. Other possible additives are mineral and vegetable oils.

It is possible to use colorants such as inorganic pigments, for example iron oxide,

20    titanium oxide and Prussian blue, and organic dyestuffs, such as alizarin dyestuffs, azo dyestuffs and metal phthalocyanine dyestuffs, and trace nutrients, such as ~alts of iron, manganese, boron, copper, cobalt, molybdenum and zinc.

The fonnulations generally comprise between 0.1 and 95 per cent by weight of active

25    compounds, preferably between 0.5 and 90%.

In the fonnulations, the active compound combinations according to the invention

can be present as a mixture with other lmown active compounds, such as fungicides,

insecticides,  acaricides  and  herbicides,  and  as  mixtures  with  fertilizers  or  plant

30    growth regulators chelates or superabsorbers.
 
The active compound combinations can be employed as such, in the form of their

formulations or of the use forms prepared therefrom, such as ready-to-use solutions,

emulsifiable  concentrates,  emulsions,  suspensions,  wettable  powders,  sOluble

powders, granules and shaped articles. The application is carried out in a customary manner, for example by watering, spraying, atomizing, scattering, spreading, dry dressing, wet dressing, liquid dressing, slurry treatment of seeds, incrustation,
implantation, injection or by foam application.

When  using  the  active  compound  combinations  according  to  the  invention,  the

10    application rates can be varied within a relatively wide range, depending on the type of application. In the treatment of parts of plants, the application rates of active compound combinations are generally between 10 and 3000 g/ha, preferably between 20 and 2000 g/ha.

15    In the treatment of the soil, the application rates of active compound combinations are generally between 10 and 4000 g/ha, preferably between 20 and 2000 g/ha.

In the treatment of seeds, the application rates are generally between O.Ql and 50 glki1ogram of seed, preferably between 0.05 and 40 glkilogram of seed.

20

The good insecticidal and acaricidal activity of the active compound combinations according to the invention is demonstrated by the examples below. Whereas the

individual active compounds have weaknesses in the activity3 the combinations have an activity which exceeds a simple addition of activities.

25

A synergistic effect of insecticides and acaricides is therefore always present when the activity of the active compound combinations exceeds the total of the activities of the active compounds when applied individually.

30    The expected activity for a given combination of two active compounds can be calculated according to S.R_ Colby, Weeds~ (1967), 20-22), as follows:


If

X    is the efficacy when applying the active compound A at an application rate of !))_giha,

Y    is the efficacy when applying the active compound B at an application rate of

!!    g/ha and

10    E is the efficacy when applying the active compounds A and B at application rates of !!land!! glha,

then
 
X•Y
E=X + Y- 1'0Q•
 

Here, the efficacy is detennined in % . 0% means an efficacy which corresponds to

that of the control, whereas an efficacy of 100% means that no infection is observed.

20    If the actual activity exceeds the calculated value, then the activity of the combination is superadditive, i.e. a synergistic effect exists. In this case, the efficacy which was actually observed must be greater than the value for the expected efficacy

(E) calculated from the formula given above.

25    The invention is illustrated by the following examples:
