(54) Title: USE OF CNI-SL FORMULATIONS FOR CONTROLLING WHITE FLY

(57) Abstract: The invention relates to a method for controlling the eggs and nymphal stages of white fly by spray-applying agrochemical formulations. Said formulations comprise at least one insecticide from the group of neonicotinyls, at least one fatty alcohol ethoxylate of formula (1), at least one solvent from the group including dimethyl sulfoxide, N-methylpyrrolidone and butyl rolactone, and optionally additives


Use of CNI SL formulations for controlling whitefly

Within the large group of sucking pests such as,  for example, representatives from the orders

Heteroptera  and Homoptera,  whiteflies (genus: Aleyrodina:  family:  Aleyrodidae), among  them

species such as Trialeurodes vaporariomm and in particular Bemisia tabad are worldwide pest

species in the production of many  types of cereals and  vegetables (Byrne & Bellows, Annual

Review of Entomology (1991) 36, 431  - 457; Byrne et al., in: Whiteflies:  their bionomics, pest

status and management, Intercept, Andover, UK,  1990, pp. 227 - 267). Controlling this pest is

therefore of great economical importance. The pesticides employed for this purpose include, inter alia., those which contain insecticides from the neonicotinyl series (for example imidacloprid or

10    acetamiprid). Such a composition is sold for example under the name Corlfidor® SL 200 from Bayer CropScience (Monheim, Germany).

While these compositions are very effective against all lifecycles of the pest when they are applied

systemically (as a  pourable  solution),  they  only  afford  inefficient protection against eggs and

nymphs when applied as a spray treatment (Horowitz et al., Bulletin of Entomological Research

15    (1988) 88, 437-442). The main reason is that eggs and nymphs are located on the underside of the leaves, where they are largely immobile. In the case of a traditional spray treatment, the insecticides therefore do not reach them, in contrast to the adults, and, after they have continued their development they lead to reinfestation of the plant with pests.

It has now been found. surprisingly, that certain formulations of neonicotinyls, when applied as a

20    spray treatment, show a markedly improved effect against eggs and nymphal stages of whitefly over the established formulations when used in the same manner.

The invention therefore relates to the use of active substance formulations containing at least one insecticide from the neonicotinyl series for controlling eggs and nymphal stages of whitefly by means of spray application.

25    Formulations which are suitable for the use according to the invention contain

between 0.1 and 30% by weight of fatty alcohol ethoxylate of the formula (1),

CH;-(CH2)-,;;-CH;-+-O-CH;-CH;--J-;;-OH   (!)

in which

m    represents average values of between 8.0 and 13.0 and
 
represents average values of between 6.0 and 17.0,

between 1 and 50% by weight of active substance from the neonicotinyl group,

between  I  and  80%  by  weight  of  dimethyl  sulphox.ide,  N-methylpyrrolidone  and/or

butyrolactone, and

between 0 and 20% by weight of additives.

The plant treatment compositions according to the invention are prepared in such a way that the

components are mixed with one another in the desired ratios. In general, a procedure is followed in

which an active substance from the neonicotinyl group is initially introduced, and the remaining

constituents are then added with stirring in any desired order.

10    When preparing the plant treatment compositions according to the invention, the temperatures can

be varied within a certain range. In general, the process will be carried out at temperatures of between wee and 50°C, preferably at room temperature.

Apparatuses which are suitable for the preparation of the plant treatment compositions according

to    the  invention  are  cw;tomary  apparatuses  which  are  employed  for  the  preparation  of

15    agrochemical fonnulations.

Suitable additives which may be present in the plant treatment compositions according to the invention are further agrochemical active substances and crystallization inhibitors, wetters, emulsifiers and also water.

Plant parts are understood as meaning all aerial and subterranean parts and organs of the plants such as shoot, leaf, flower and root, examples which may be mentioned being leaves, needles, stalks, stems, flowers, fruiting bodies, fruits and seeds, and also roots, tubers and rhizomes. The plant parts also include harvested material and vegetative and generative propagation materiaJ, for example cuttings, tubers, rhizomes, slips and seeds.

25    What must be emphasized here is the especiaJly advantageous effect of the compositions according to the invention regarding the use in cereal plants such as, for example, wheat, oats, barley, spelt, triticale and rye, but also in maize, millet and sorghum, rice, sugarcane, soybeans, sunflowers, potatoes, cotton, oilseed rape, canola, tobacco, sugar beet, fodder beet, asparagus, hops and fruit
plants (comprising pome fruit such as, for example, apples and pears, stone fruit  such  as, for

30    example, peaches, nectarines, cherries, plums and apricots, citrus fruits such as, for example, oranges, grapefruits, limes, lemons, cumquats, tangerines and satsumas, nuts such as, for example, pistachios, almonds, walnuts and pecan nuts, tropical fruits such as, for example, mango, papaya,

pineapple, dates and bananas, and grapes) and vegetables (comprising leafy vegetables such as, for

example,  endives,  com  salad,  Florence  fennel,  lettuce,  cos  lettuce,  Swiss chard,  spinach  and

chicory, cabbages such as, for example, cauliflower, broccoli, Chinese leaves, borecole (curly kale,

feathered cabbage), kohlrabi, Brussels sprouts, red cabbage, white cabbage and savoy cabbage,

fruit  vegetables  such  as,  for  example,  aubergines,  cucumbers,  capsicums,  table  pumpkins,

tomatoes, courgettes and sweet com, root vegetables such as, for example, celeriac, early turnips,

carrots, including yellow cultivars, radish, including small radish, beetroot. scorzonera and celery,

pulses such as, for example, beans and peas, and bulb vegetables such as, for example, leeks and

table onions).

10    The treatment according to the invention of the plants and plant parts with the fonnulations according to the invention is carried out by spraying. vaporizing or misting. preferably by spraying.

The agrochemical active substances which are present display a better biological activity against all stages of whitefly than when applied in the fonn of the corresponding traditional fonnulations.

15    The invention is illustrated by the examples which follow. The examples are not to be construed as limiting.

Prenaration example

To prepare formulation,

20 g    of imidacloprid

are treated with stirring at room temperature in succession with

5 g    of  the  polyvinylpyrrolidone/polyvinyl  alcohol  copolymer  known  as  Luviskol  VA  64

(BAS F),

10 g    of the fatty  alcohol  ethoxylate  of the formula  (I) which  is  known  as  Genapol  CMlOO

(Clariant), in which

m    represents the avernge value of 10.5 and
lO    represents the average value of 8.4,

and

65 g    ofN-methylpyrrolidone.

After the addition has ended, stirring is continued for 5 minutes at room temperature. This gives a homogeneous fluid.

Cotton plants (Gossypium hirsutum) which are infested with whitefly (Bemisia tabaci) eggs and

larvae are sprayed with a composition of the desired composition and concentration.


After the desired time, the destruction is detennined in%. In this context, 100% means that all of the animals were destroyed; 0% means that no animals were destroyed.
