Description

BACKGROUND OF THE INVENTION

1. Field of the Invention

This invention is directed to novel phenylhydrazine derivatives which exhibit activity as insecticides, acaricides and nematicides. This invention is also directed to insecticidal, acaricidal or nematicidal compositions comprising such compounds as well as to methods of controlling insects, acarids and nematodes employing such compounds or compositions.

Destruction by insects, acarids and nematodes presents a serious problem to agriculture. A wide variety of field crops are in need of protection from nematodes, acarids, and insects including such valuable crops as soybeans, corn, peanuts, cotton, alfalfa, rice and tobacco. In addition, vegetables, such as tomatoes, potatoes, sugarbeet, carrots, peas, and the like as well as fruits, nuts, ornamentals and seed bed crops such as apples, peaches, almonds, citrus fruit and grapes may also require protection from the ravages of such pests.

Consequently, the development of new, more effective pesticides including insecticides, acaricides and nematicides represents an ongoing scientific activity. More particularly, the development of pesticides which are effective as both ovicides and larvicides are of interest. 2. Description of Related Art

The present invention is also directed to a method for controlling pests such as insects, acarids or nematodes which comprises applying an effective amount of a compound of formula (I) or (II) or of a composition of the present invention to a locus to be protected or rid of pests.

DETAILED DESCRIPTION OF THE INVENTION

The compounds of the present invention have the structure (I) or (II) defined above. Preferred compounds are those in which Y is hydrogen or COCF.sub.3.

The compounds having structure (I) may be prepared by reacting a substituted phenylhydrazine: ##STR3## with an acylating agent: ##STR4## wherein Z is halo or ##STR5## and an equivalent of an HCl acceptor such as pyridine in a solvent such as toluene. The product of this reaction may be further acylated, or converted by oxidation with an oxidizing agent such as Pd/air to form compounds having structure (II).

The compositions of this invention comprise (a) a compound having a structure within that of formula (I) or (II) above, and (b) a suitable carrier. Such suitable carriers may be solid or liquid in nature.

Suitable liquid carriers may be comprised of water, alcohols, ketones, phenols, toluene and xylenes. In such formulations, additives conventionally employed in the art may be utilized such as, for example, one or more surface active agents and/or inert diluents, to facilitate handling an application of tile resulting pesticide composition.

The pesticidal compositions may alternatively comprise solid carriers taking the form of dusts, granules, wettable powders, pastes, aerosols, emulsions, emulsifiable concentrates, and water-soluble solids.

For example, the pesticidal compounds of this invention may be applied as dusts when admixed with or absorbed onto powdered solid carriers, such as mineral silicates, e.g., mica, talc, pyrophyllite and clays, together with a surface-active dispersing agent so that a wettable powder is obtained which then is applicable directly to the loci to be treated. Alternatively, the powdered solid carrier containing the compound admixed therewith may be dispersed in water to form a suspension for application in such form.

Granular formulations of the compounds, suitable for application by broadcasting, side dressing, soil incorporation or seed treatment, are suitably prepared using a granular or pellitized form of carrier such as granular clays, vermiculite, charcoal or corn cobs.

Alternatively, the pesticidal compounds may be applied in liquids or sprays when utilized in a liquid carrier, such as in a solution comprising a compatible solvent such as acetone, benzene, toluene or kerosene, or as dispersed in a suitable non-solvent medium, for example, water.

Another method of application to loci to be treated is aerosol treatment, for which the compound may be dissolved in an aerosol carrier which is a liquid under pressure but which is a gas at ordinary temperature (e.g., 20.degree. C.) and atmospheric pressure. Aerosol formulations may also be prepared by first dissolving the compound in a less volatile solvent and then admixing the resulting solution with a highly volatile liquid aerosol carrier.

For pesticidal treatment of plants (such term including plant parts), the compounds of the invention preferably are applied in aqueous emulsions containing a surface-active dispersing agent which may be non-ionic, cationic or anionic. Suitable surface-active agents include those known in the art, such as those disclosed in U.S. Pat. No. 2,547,724 (columns 3 and 4). The compounds of the invention may be mixed with such surface-active dispersing agents, with or without an organic solvent, as concentrates for the subsequent addition of water to yield aqueous suspensions of the compounds at desired concentration levels.

In addition, the compounds may be employed with carriers which themselves are pesticidally active, such as insecticides, acaricides, fungicides or bactericides.

It will be understood that the amount of the pesticidally active compound in a given formulation will depend upon the specific pest to) be combatted, as well as upon the specific chemical composition and formulation of the compound being employed, the method of applying the compound/formulation and the locus of treatment so that the pesticidally effective amount of the compound may vary widely. Generally, however, concentrations of the compound as the active ingredient in pesticidally effective formulations may range from about 0.1 to about 95 percent by weight. Spray dilutions may be as low as a few parts per million, while at the opposite extreme, full strength concentrates of the compound may be usefully applied by ultra low volume techniques. Concentration per unit area, where plants constitute the loci of treatment, may range between about 0.01 and about 50 pounds per acre, with concentrations of between about 0.1 and about 10 pounds per acre preferably being employed for crops such as corn, tobacco, rice and the like.

To combat pests, sprays of the compounds may be applied to the pests directly and/or to plants upon which they feed or nest. The pesticidally active formulations may also be applied to the soil or other medium in which the pests are present.

Harmful insects, nematodes and acarids attack a wide variety of plants, including both ornamental and agricultural plants and inflict damage by consuming roots and/or foliage, withdrawing vital juices from the plants, secreting toxins and often by transmitting diseases. The compounds of the present invention may be advantageously utilized to minimize or prevent such damage. The specific methods of application, as well as the selection and concentration of these compounds will, of course, vary depending upon such circumstances as geographic area, climate, topography, plant tolerance, etc. For specific circumstances, one skilled in the art may readily determine the proper compound, concentration and method of application by routine experimentation.

The compounds of the invention are particularly useful as insecticides, nematicides and acaricides, for foliar and/or soil application.

Example 10

Preparation of Formulations

The remaining examples relate to the pesticidal use of the compounds of this invention. In all these examples a stock solution for the compounds were prepared at 3000 ppm by dissolving 0.3 gram of the compound to be tested in 10 ml of acetone and adding 90 ml of distilled water plus for drops of ethoxylated sorbitan monolaurate, or a similar suitable wetting agent. For each example that follows, this stock solution was used and the specified dilutions made. All the tests discussed below, which involved treatment with compounds of this invention, were always repeated with controls, in which the active compound was not provided, to permit a comparison upon which the percent control was calculated.

EXAMPLE 11

Mite Adulticide and Mite Ovicide/Larvicide Tests

One day before treatment, a "FIG. 8" configuration of tree tanglefoot was applied to each of two cowpea primary leaves, one from each of two plants in a pot. In each figure, the circle nearer the stem was designated for the mite ovicide/larvicide test and the circle further from the stem was designated for the mite adulticide test.

Groups of adult mites (Tetranychus urticae Koch) were transferred into ovicide circles one day before treatment and the females were allowed to deposit eggs until one hour before treatment when they were removed. Plants were sprayed to run off with a 1000 ppm solution diluted from the 3000 ppm stock solution.

One day following treatment, groups of approximately 25 adult mites were transferred into the adulticide rings. Five days later these rings were examined for live mites remaining on the leaves. The percent control was estimated based on the number of mites surviving on the check plants.

Nine days following treatment the ovicide/larvicide rings were examined for hatched eggs and living immature mites. The percent control was estimated based on the number of eggs hatching and immature mites surviving on the check plants. When the treatment effect was to eggs, control was designated as ovicidal (O); when the treatment effect was to immatures, control was designated as larvicidal (L).

Example 12

European Red Mite Test

Orchard apple trees with infestations of European red mite (Panonychus ulmi) were sprayed with aqueous solutions of emulsifiable concentrates of individual compounds. Greater than 75 percent control with an application rate of 150 ppm ai was achieved by compound numbers 103, 10, 11, 19, 20, 25, 26, and 82.

Example 13

Nematode Test

The stock solution of 3000 ppm was diluted to 1000 ppm. For each compound, 25 ml was drenched onto 500 grams of soil infested with root knot nematode (Meloidogyne incognita) eggs in a pot, for a soil concentration of 50 ppm sc.

One day after treatment, two tomato seedlings were planted in each pot. Nineteen days after planting, the roots were evaluated for the presence of knots or galls, and the percent control was estimated based on the infestation levels in check plants.

The results of the testing of nematodes (NE) are given in Table 6.

Example 14

Rice Planthopper Foliar Test

The stock solution of 3000 ppm was diluted to 1000 ppm. One pot containing approximately 20 Mars variety rice seedlings was treated with each formulation by spraying with a spray atomizer. One day after treatment plants were covered with a tubular cage and twenty adult rice delphacids, Sogatodes oryzicola, were transferred into each cage. Five days after transferring, counts were made of the surviving planthoppers in each pot and percent control was estimated. The results of the testing of rice planthoppers (RPH) are given in Table 6.

Example 15

Tobacco Budworm Test

The stock solution of 3000 ppm was used for this test. For each compound, 0.2 ml was pipetted onto the surface of each of 5 diet cells, allowed to spread over the surfaces and air dried for two hours. Then a second istar Heliothis virescens larva was introduced into each cell. After 14 days, the number of living larvae was determined for each treatment and percent control, corrected by Abbott's formula, was calculated.

The results of the testing of tobacco budworms (TB) are given in Table 6.

Example 16

Southern Corn Rootworm

The stock solution of 3000 ppm was diluted to 100 ppm. For each compound, 2.5 ml was pipetted onto a filter paper (Whatman #3) at the bottom of a 100 mm petri dish. Two corn seedlings were soaked in the 100 ppm solution for 1 hour and transferred to the petri dish. After 24 hours, each dish was loaded with 5 second instar larvae of Diabrotica undecimpunctata. After five days, the number of live larvae were noted and the percent control, corrected by Abbott's formula (see J. Economic Entomology, 18, 265-267 (1925)) was calculated.

The results appear in Table 6.
