Also included herein is a method of preparing, using, and applying the compositions.

The compounds herein described can be prepared by several methods. One such general method applicable in preparing the compounds is the condensation between the appropriate substituted phosphorus-com taining oxy or thio benzaldehyde, e.g., phosphoro, phosphono, and phosphino, and hydroxylarnine hydrochloride in order to prepare the corresponding benzaldoxime. The benzaldoxime can be further reacted with appropriate substituted isocyanate, substituted acid chlorides, substituted chloroforrnate, substituted chlorothiolformate, substituted sulfonyl chloride, monosubstituted carbamyl chloride, N,N-disubstituted carbamyl chloride, substituted phosphoryl chloride, substituted thionophosphoryl chloride, or anhydrous trichloro-acetaldehyde. When R is to be lower alkyl, an appropriate substituted-phosphoryl or substituted-thiophosphoryl lower alkyl phenylketone is condensed with hydroxylamine hydrochloride to prepare the corresponding ketoxime. Another method useful for the preparation of carbamyl derivatives is first the condensation of phosgene with the aldoxime followed by the condensation with a primary or secondary amine. The reactions proceed readily in the liquid phase. The employment of a solvent is also useful, facilitating processing, as well as agitation of the reactants. Solvents such as water, benzene, toluene, chloroform, aqueous ethanol and the like, can be employed. When using derivatives containing the aldoxime, it is preferred to carry out the reaction in the presence of a hydrogen halide acceptor such as sodium carbonate, triethylamine, pyridine, picoline and the like, which are used as catalysts. Similarly, in the condensation reaction to prepare secondary carbamyl derivatives, the reaction is preferably conducted in the presence of a hydrogen halide acceptor.

The reactions are carried out at temperatures that permit operation in the liquid phase. These temperatures are between about room temperature and reflux temperature of the solvent, if one is employed. Preferably, the reaction mixture is refluxed, usually at an elevated temperature. The ketoxime can be reacted with functional moieties as described supra for the benzaldoxime.

it now has been discovered that the new compositions disclosed herein are distinguished as useful as insecticides, herbicides, foliar fungi protectants and are particularly effective as systemic parasiticidal agents for animals.

inch deep in Santa Cruz sandy loam soil contained in compressed paper flats 8 A X 6 inches, which are 2 inches deep. Enough seeds were planted to give' about thirty to fifty plants of each of the weed species In the method of the present invention for con- 45 in each flat. The flats were watered after planting. The following day each flat was sprayed at the rate of 20 pounds of the candidate compound under test in 80 gallons of solution per acre. An atomizer was used to spray the solution on the soil surface. The flats were placed in a greenhouse at 80 F. and watered regularly. Two weeks later the degree of weed control was determined by comparing the amount of germination and growth of each weed in the treated flats with weeds in several untreated control flats. The results of this test are reported in Table II.

Post-emergence Herbicide Test. The seeds of four weed species, crab grass (CG) (digitaria sanguinalis (L.) Scop.), watergrass (WG) (Echinochloa crusgalli (L.) Beauv.), red oats (R0) (Avena sativa (L.)), mustard (Md) (Brassica juncea (L.)

In practice, the compounds are formulated with an inert carrier, utilizing methods well known to those skilled in the art, thereby making them suitable for application as dusts, sprays, or drenches and the like in the form and manner required. The mixtures can be dispersed in water with the aid of a wetting agent or they can be employed in organic liquid compositions, oil and water, water in oil emulsions, with or without the addition of wetting, dispersing or emulsifying agents. The amount applied depends upon the nature of the seeds or plants to be controlled and the rate of application varies from 1 to approximately 50 pounds per acre.

The phytotoxic compositions of this invention are applied to the plants in the conventional manner. Thus, the dust and liquid compositions can be applied to the plant by the use of power-dusters, boom and hand sprayers and spray-dusters. The compositions can also be applied from airplanes as a dust or a spray because they are effective in very low dosages. In order to modify or control growth of germinating seeds or emerging seedlings, the dust and liquid compositions are applied to the soil according to conventional methods and are preferably distributed in the soil to a depth of at least one-half inch below the soil surface. It is not necessary that the phytotoxic compositions be admixed with the soil particles and these compositions can be applied merely by spraying or sprinkling the surface of the soil. The phytotoxic compositions of this invention can also be applied by addition to irrigation water supplied to the field to be treated. This method of application permits the penetration of the compositions into the soil as the water is absorbed therein. Dust compositions, granular compositions or liquid formulations applied on the surface of the soil can be distributed below the surface of the soil by conventional means such as discin g, dragging or mixing operations.

The phytotoxic compositions of this invention can also contain other additaments, for example, fertilizers, pesticides and the like, used as adjuvant or in combination with any of the above-described adjuvants. Phytotoxicants useful in combination with the abovedescribed compounds include for example 2,4- dichlorophenoxyacetic acids, 2,4,5-trichlorophenoxyacetic acid, 2-methyl-4-chlorophenoxyacedc acid and the salts, esters and amides thereof; triazine derivatives, such as 2,4-bix( 3-methoxy-propylamino)-6- methylthio-Striazine; 2-chloro-4-ethylamino-6- isopropylamino-S-triazine, and 2-ethylamino-4- isopropylamino-6-methylmercapto-S-triazine; urea derivatives, such as 3-(3,4-dichloropheny1)-l ,1- dimethyl urea and 3-(p-chloropheny1)-l l-dimethyl urea, and acetamides such as N,N-diallyluchloroacetarnide, N-(a-chloroacetyl)hexamethylene imine, and N,N-diethyl-a -bromoacetamide, and the like; benzoic acids such as 3-amino-2,5-dichlo'robenzoic and; thiocarbarnates, such as S -propyl dipropylthiocarbamate; S-ethyldipropylthiocarbamate, S-ethyl-cyclohexylethylthiocarbarnate, S-ethyl hexahydro-1H-azepine-l-carbothioate and the like. Fertilizers useful in combination with the active ingredients include, for example, ammonium nitrate, urea and superphosphate. Other useful additaments include materials in which plant organisms take root and grow such as compost, manure, humus, sand and the like.

The compositions of the present invention were tested as foliage fungicides. This test indicated protectant action against fungi attacking plant foliage. Pinto bean plants were sprayed with three concentrations of dissolved or suspended chemical in water, 1,000, 500 and 100 parts per million (ppm). The active compound was dissolved in an appropriate solvent and further dispersed in water, and for this purpose a surface active agent or wetting agent was employed to facilitate formulation of the dispersions. After the sprayed plants were dried, they were inoculated with powdery mildew spores (Erysiphe polygoni). Results were read when disease symptoms were distinct on untreated bean plants. Compound numbers 84 and 86 exhibited 75-99 percent control at 100 ppm. and compound number 85 exhibited 100 percent control at 100 ppm. of the powdery mildew infection with no phytotoxicity.

Insecticidal Evaluation Tests.

The following insect species were subjected to evaluation tests for insecticidal activity:

1. Housefly (HF) Musca domestica (Linn.)

2. German Roach (GR) Blattella germanica (Linn.)

3. Salt-marsh caterpillar (SMC) Estigmene acrea 4. Milkweed Bug (MWB) Oncopeltus fasciatus (Dallas) 5. Lygus Bug (LB) Lygus hesperus (Knight) Aliquots of the toxicants, dissolved in an appropriate solvent, were diluted in water containing 0.002 percent of a wetting agent, Sponto 221 (a polyoxyether of alkylated phenols blended with organic sulfonates). Test concentrations ranged from 0.1 percent downward to that at which 50 percent mortality was obtained. In the tests, for these species, l-month old nymphs of the German Cockroach and Lygus Bug and 2-week old nymphs of milkweed bug were placed in separate circular cardboard cages sealed on one end with cellophane and covered by a cloth netting on the other. Test concentrations for the Lygus Bug ranged from 0.05 percent downward to that at which 50 percent mortality was obtained. Each of the aqueous suspensions of the candidate compounds were sprayed onto the insects through the cloth netting by means of a hand spray gun. Percent mortality in each case recorded after 72 hours and the Ld-SO values expressed as percent of toxicant in the aqueous spray was recorded.

For testing the Salt Marsh Caterpillar, test solutions were prepared in an identical manner and at concentrations the same as for the German cockroach and the milkweed bug above. Sections of bitter dock (Rumex obtusifolus) leaves, 1 -1.5 inches in length were immersed in the test solutions for 10 to 15 seconds and placed on a wire screen to dry. The dried leaf was placed on a moistened piece of filter paper in a Petri dish and infested with 5-3rd lnstar larvae. Mortality of the larvae was recorded after 72 hours and the LD-SO values are expressed as percent active ingredient in the aqueous suspension.

The following procedure was used to test houseflies. A stock solution containing IOOug/mI of the toxicant in an appropriate solvent was prepared. Aliquots of this solution were combined with 1 milliliter of an acetonepeanut oil solution in a glass Petri dish and allowed to dry. The aliquots were there to achieve desired toxicant concentration ranging from 100p. g per Petri dish to that at which 50 percent mortality was attained. The Petri dishes were placed in a circular cardboard cage, closed on the bottom with cellophane and covered on top with cloth netting. Twenty-five female houseflies were introduced into the cage and the percent mortality was recorded after 48 hours. The LD-50 values are expressed in terms of ,u. g per 25 female flies. The result of these insecticidal evaluation tests are given in Table IV.

In testing against milkweed bug representative LD-50 results obtained were for compound numbers 47, 55 and 56 0.01 percent; for compound numbers 49, 67 and 143 0.03 percent; compound number 64 0.05 percent; compound number 68 0.08 percent and compound number 54 0.008 percent.

Compound number 55 is extremely useful in the control of European corn borer (Pyrausta nubilalis (Hubner)).

The same test procedure as mentioned above for salt marsh caterpillar was used for cotton bollworm (Heliothis zea (Boddie)), except that leaves of Romaine lettuce were utilized as the host plant rather than bitter dock. The following compounds were found to be active against cotton bollworm: the LD-SO values obtained were (5), (54) and (143) 0.005 percent; 10) 0.01 percent; (13) 0.03 percent; (137) 0.001 percent; (55), (138), (141 and (142) 0.003 percent; and (56) 0.008 percent.

The compounds were also found to be active against two-spotted mite (Tetranychus urticae (Koch)). Lima bean plants (Phaseolus sp.) were utilized as the host plant and infested with 50 to mites of various ages. Twenty-four hours after infestation, they were sprayed to the point of run off with aqueous suspension of the toxicant. Test concentrations range from 0.05 percent to that at which 50 percent mortality was obtained. The following compounds exhibited LD-SO values of 0.005 percent (9) and (56); 0.001 percent (55) and 0.008 percent (46).

The compounds were also found to be active against black bean aphid (Aplulsfabae (Scop.)). The same test procedure as given for the two-spotted mite above was used for black bean aphid except that nasturtium (Tropaeolum sp.) plants approximately 2 to 3 inches tall were used as the host plant. The following compounds exhibited LD-SO values of 0.005 percent (40); 0.005 percent (55); 0.003 percent (37); 0.003 percent (38); 0.003 percent (65); 0.008 percent (56); and 0.008 percent (64).

Animal Systemic Evaluation Tests Candidate test compounds, usually formulated in Tween-20 (polyoxyethylene (20) Sorbitan monolaurate), are administered orally by stomach tube at an initial dosage of 400 mg./Kg. to fasted male Swiss albino mice. Two hours after treatment, the mice are killed by cervical dislocation and both thighs are dissected from each test animal and placed in labeled glass vials. Each vial is inoculated with 10 newly hatched black blow fly larvae (Phormia regina (Meigen)) and stored in an incubator at F. and 40-50 percent relative humidity. Tissues from mice that die during the 2 hour holding period after administration of the compounds are processed in the same manner. After the larvae had fed on the tissues for 48 hours, the vials are examined and the percentage of larvae mortality in each is noted. If 80 percent or more of the larvae are killed at the initial dosage, successively lower dosages are then tested until the lowest dosage that killed at least 80 percent of the larvae is determined.

In this animal systemic insecticide evaluation test, compounds are tested further on guinea pigs, using the oral route of administration. The compounds are formulated as solutions or suspensions in Tween 20 and administered at an initial dosage of mgJKg. Twenty-four hours prior to treatment, the guinea pigs are wounded and the wounds infested with larvae of the black blow fly (Phormia regina (Meigen)). At 4 and 24 hours after treatment, stable flies (Stomoxys calcitrans (13.)) are fed on the guinea pigs. Engorged flies are held for 24 hours to see if they are killed by the blood they ingest. At 24 hours after treatment, the wounds are examined to see if the fly larvae are killed by the insecticide. If the larvae are alive, they are removed from the wounds. If any of the arthropods are killed at the initial dosage, the candidate insecticides are administered at lower dosages until there was no significant insecticidal activity. The following table gives the results of the mouse assay and guinea pig assay tests described above.

The test results indicate that these compounds are biologically active and are useful as animal systemic insecticides. The compounds can be used as effective parasiticides by applying them in a variety of ways and at various concentrations, depending upon the nature and habitat of the parasite to be controlled.

In this test unfed lone star tick nymphs (Amblyomma americanum (L.)) were confined for 24 hours in cotton cloth that had been treated in acetone solutions of the test compounds. The percentage of nymphal mortality was then observed. If 80 percent or more of the nymphs were killed at the initial screening level of 1.0 percent for a given compound, the compound was tested further at lower levels. The compounds 5,11,17, 20, 23, 26, 31, 33, 36, 38, 61, 64 and 65 exhibited 80 percent or better control of the tick nymphs at 0.5 percent. Compound number 29 ex hibited 80 percent or better control of the tick nymphs at 0.1 percent and compound number 32 exhibited 80 percent or better control at 1.0 percent concentrations. Compound number 28 at a concentration of 0.05 percent was better than 80 percent lethal to tick nymphs.
