Background and Bummary of Invention ee mr ee et em et ert 0 i te ee fe on tm
The present invention recognizes that N’- substituted-N,N’'~diacylhydrazines have properties which make them particularly useful for controlling insects in rice crops. Additionally, compositions containing these compounds are also useful as insecticides in rice crops. More specifically, the invention relates to compositions : and a method for controlling insects in the locus of a rice field with an insecticidally-effective amount of a compound of the formula:r 0 0 fl ]

Colalkoxy and 2- or 3- (Cy-Cp)alkoxyj ‘ar 1m 1- methylethenyl, phenyl or phenyl substituted with one or two substituents each independently selected from 2-, 3-, or 4-halo, 3,5 3,4~ or 2,4 dihalo, 3-

S The term halo as it applies to this invention means chloro, fluoro, bromo and iodo atoms.
The preferred moiety for the R substituent is tert-butyl. Preferred moieties for the A substituent are phenyl and substituted phenyl wherein the substituents are 4-halo, 4-(Ci{-Calalkyl or 2,3-di(C{-Cplalkyl or 2,6-dihalo, preferably 2,46~di fluoro. Preferred moieties for the a’ substituent are subutituted phenyls wherein the . } substituents are 2-halo, 2,4-dihalo, 3-(Cy4~Ca)alkyl of 3,5-di (Cy-Cp) alkyl.
More preferred moieties for the A substituent are phenyls substituted with 4-methyl, 4-ethyl, 2,4-difluora or 2,3-dimethyl and more preferred moieties for the A’ substituent are phenyls - 20 sibati tuted with 2-chloro, 2,4-dichloro, - 2-chloro- a-f1uora, 3-methyl or 3,85-dimethyl.

The compounds of Formula I exhibit weveral properties which make them particularly } advantageous for use in rice crops and for use in . 3 pasticidal compositions used in rice. For sxample, the compounds exhibit high toxicity against many important insects which {invade rice, "including those of the orders Lepidoptera and Homoptera.
Another advantage of the compounds of Formula
I is their low toxicity against mammals, birds, crustaceans and fish as well as beneficial insects : such as lady beetles, which feed on aphids and scale pests, spiders, flys, wasps and true bugs of i . the order Hemiptera. This makes these compounds 13 particularly suitable for use in rice since fish and crustaceans, e.g., shrimp, are often raised in rice paddies and geese and ducks are often used to control other insects in the vicinities of rice paddies. Moreover, rice paddy water usually flows — 20 or migrates into other water sources which are used i by mammals, birds, crustaceans and fish. i‘ - The diacylhydrazines of Formula I are readily . absorbed by the rice root system and’ exhibit systemic activity in the rice. This property makes 29 the compounds particularly useful in controlling : rice borers which are difficult to codtrol by : foliar dust or spray applications of insecticides.
Moreover, the systemic distribution of the compounds in the rice plants may result in the need a
2a} for fewer applications. Additionally, because the compounds cause little adverse effect on rice, the compounds are particularly useful in rice where phytotoxicity effects are consi dered highly 3 undesirable.
The compounds used in the present invention are useful against rice Lepidoptera belonging to the families: (1)Pyralidae, rice borers, for example, spotted stalk borer (Chilo | partellus (8winhoe) , rice stem borer (Chilo suppressalis(Wlk.)), white rice borer (Maliarpha separatella Rag.), rice case worm {(Nymphula depunctalis (Gn.)), rice leafroller (Cnaphalocrocis meadinalis(Buen.)) and yellow and white paddy stem borers (Tryporyza incertulas (Wlk.) and To innotata (Wlk.))y (2) Noctuidae, rice —— for example, Mythimna unipuncta (Haw.) M., separata (Wlk.) and HM. loreyi (Dup.), purple stem borer (Seasamla inferens (Wlk.)), beet armyworm (Spodoptera exigua (Hb.)) and paddy armyworm : (Spodoptera mauritia (Boisd.))y and (3) Hasperidae, . rice skippers, for example rice skippers (Telicota ! augias(L.)), Pelopidas mathias(F.)) rice leaf R scaler (Parnara guttata (Bremer Brey), and
Ampittia dioscorides. ’ :
The compounds used in the present invention are almo useful against rice Homoptera belonging to the families: (1) Cicadellidae, lwafhoppars, for example, green leafhoppers (Nephotettix cinctinceps '
- Da 14 26417 © {Uh1.) and Nephotettix impicticeps Ishiwara), green rice leafhopper (Nephotettix nigropictus (Stal.)) and zig-zag winged leafhopper (Inazuma dorsalis (Matsch.)); and (2) Delphacidae, planthoppers, for : 5 example, brown planthopper (Nilaparvata lugens (Stal.).
The compounds used in the present invention are especially effective against larvae of
Lepidoptera, particularly rice stem borer (Chilo suppressalis (Wik.)), rice leaf folder or rice leaf roller (Cnaphalocrocis medinalis (Buen), rice
RrMyWor ms (Spodoptera sp.)) and rice skipper (Telicota augias (L.)) and nymphs of Homptera, ‘ particularly green rice leafhopper (Nephotettix cincticeps (Uhl)). oo
