DESCRIPTION:

BRIEF SUMMARY
This application is a 371 of PCT/KR92/0005, filed Feb. 25, 1992.


TECHNICAL FIELD

The present invention relates to novel pyridine sulfonyl urea derivatives having agriculturally suitable for herbicidal activity.


BACKGROUND OF THE INVENTION

It is publicly well known that sulfonyl urea derivatives have a herbicidal activity. Here are the formulas for the sulfonyl ureas. formula ##STR3## wherein, L is OH, ##STR4## R is H, F, Cl, Br, NO.sub.2, CF.sub.3 or C.sub.1 -C.sub.3 alkyl or alkoxy; R.sup.1 is H or C.sub.1 -C.sub.4 alkyl; formula ##STR5## wherein, R.sup.1 is F, Cl, Br, C.sub.1 -C.sub.4 alkyl, OH, alkoxy, alkylthio or C.sub.1 -C.sub.2 alkyl substituted with phenyl group; formula ##STR6## wherein, Q is C.sub.1 -C.sub.4 alkyl substituted with R.sup.2 ; ##STR7## R.sup.3 is H, C.sub.1 -C.sub.4 alkyl; L is ##STR8## R.sup.12 is H or CH.sub.3. 4) European Patent No. 125,205 discloses the compound having the following formula ##STR9## wherein, R.sup.6 is H, alkyl or F; formula ##STR10## wherein, L is OR.sup.9 ; formula ##STR11## wherein, n is 0 or 1; alkoxy. formula ##STR12## wherein, Q is linear --(CH.sub.2).sub.n -substituted with C.sub.1 -C.sub.3 haloalkyl; formula ##STR13## wherein, R.sup.1 is H, Cl, Br, F, alkyl, alkoxy, alkylthio or CO.sub.2 R.sup.5. substituted with R.sup.1 on 3-position, wherein R1 is H, Cl, Br, F, alkyl, alkoxy, alkylthio, CO.sub.2 R.sup.5 or SO.sub.2 NR.sup.6 R.sup.7. having the following formula ##STR14## wherein, R.sup.4 is H, Cl, Br, F, alkyl, alkoxy, NO.sub.2, CO.sub.2 R.sup.6 or SR.sup.13. formula ##STR15## wherein, R.sup.3 is H, Cl, Br, F, CO.sub.2 R.sup.11 or SOnR.sup.12. formula ##STR16## wherein, R is alkyl, alkenyl, CF.sub.3, CHF.sub.2 or CH.sub.2 CF.sub.3 ; sulfonyl urea compound having the following formula ##STR17## wherein, A is ##STR18## R.sup.2 is H, Cl, Br, F, alkyl, alkoxy, CO.sub.2 R.sup.5, SOmR.sup.6, SO.sub.2 NR.sup.18 R.sup.19 or SO.sub.2 N(OCH.sub.3)CH.sub.3. 125,846/155,767/161,905/164,269/171,286 disclose pyridine sulfonyl urea substituted with Cl, Br, SO.sub.2 R or SO.sub.2 NR.sup.1 R.sup.2 on 2- or 3-position. having the following formula ##STR19## wherein, R.sup.2 is H, alkyl, haloalkyl, halogen, NO.sub.2, alkoxy, ##STR20## SO.sub.2 NR.sup.6 R.sup.7 or SOnR; R.sup.3 is H, halogen, alkyl, OCH.sub.3, NO.sub.2 or CF.sub.3 ; --CO.sub.2 R or alkoxy. having the following formula ##STR21## wherein, X is O, S, SO or SO.sub.2 ; alkylsulfonyl. having the following formula ##STR22## wherein, R.sup.1 is alkylsulfonyl or dialkylamino sulfonyl group; urea having the following formula ##STR23## wherein, R.sup.1 is Q alkyl or SO.sub.2 N R.sup.4 R.sup.5 ; compound having the following formula ##STR24## wherein, R.sup.3 is H, F, Cl, Br, NO.sub.2, OCH.sub.3 or CF.sub.3 ; formula ##STR25## 21) U.S. Pat. No. 4,747,870 discloses O-alkylcarbonyl pyridine sulfonyl urea compound, and U.S. Pat. No. 4,838,926 discloses O-substituted alkylpyridine urea compound. And, U.S. Pat. No. 4,747,337 discloses the compound having the following formula ##STR26## wherein, J is ##STR27## R.sup.1 is H, alkyl, haloalkyl, halogen, NO.sub.2, alkoxy, alkylthio or CN; cycloalkylthio, SO.sub.2 R.sup.8, SO.sub.3 R.sup.8 N.sub.3, CN, CH.sub.2 F, CHF.sub.2, CH.sub.2 Cl, haloalkyl or PO(O alkyl).sub.2.
As the above patents, many sulfonyl urea herbicides have known until recently.
Even with these herbicides, more and more weeds develop immunity forwards these herbicides and cause undesirable vegetations. Thus, continuous research is in demand to develop more effective and newer for a good harvest.
Therefore, the object of the presentation is to invent a new pyridine sulfonyl urea derivative having a very prominent herbicidal activity with a good selectivity for various vegetations and agriculturally suitable herbicides for treatment of pre-emergence and/or post-emergence or plant growth regulants.


SUMMARY OF THE INVENTION

The present invention relates to novel pyridine sulfonyl urea derivatives having the following formula (I) ##STR28## wherein, P is P-1, P-2, P-3 or P-4 as follows; ##STR29## E is singl
