1. CHEMICAL CONTROL OF INSECTS)
2. HISTORY -USE OF INSECTICIDE BEGAIN IN 1850-1860 AGAINST POTATO BEETLEPARIS GREEN WAS USED AGAINST BEETLE
3. HISTORY: -BETWEEN 1900-1940 FLOURINE COMPOUND AND PLANT DERIVED INSECTICIDES WERE DEVELOPEDDAWN OF CHEMICAL INSECTCIDE BEGAIN WITH DISCOVERY OF -[DDT] IN 1940
4. HISTORY: -LATER MANY HARMFUL INSECTICIDES WERE PRODUCED IN WORLD WAR 2 WHICH LATER BANNED-DDT, BHC, ALDRIN, CaCN, ENDRIN,DIELDRIN,CARBOFURAN, ENDOSULFAN …..ETC
5. CLASSIFICATION : -INORGANIC PESTICIDES-ARSENICAL,FOUORINE COMPOUND,SULPHUR DERIVATIVES ORGANIC PESTICIDES- PLANT ORIGIN, ANIMAL ORIGIN, SYNTHETIC ORGANIC PESTICIDES
6. PLANT ORIGIN PESTICIDENICOTINEPYRETHRUMROTENONEAZADIRACHTIN
7. NICOTINEOBTAINED FROM PLANT Nectana tobacumCHEMICAL FORMULA-IT IS A CONTACT POISONENERS THROUGH TRACHEAE AND CUTICLEIT IS SAFE TO USE IN VARIOUSPLANTS
8. NICOTINEIT IS EXPENSIVEIT KILLS MANY PEST SPECIES AND BLOCK THE GROWTH OF SOME HARMFUL MICROBES ALSO
9. PYRETHRUMOBTAINED FROM FLOWERS OF Chrysanthemum roseumC.carneumIT IS APPLIED AS SPRAY OR DUST
10. PYRETHRUMIT LOSES TOXIC PROPERTIES WHEN EXPOSED TO SUNLIGHT,UV,AIR OR HEAT.USED AGAINST FLIES, BED BUG SILVER FISH
11. ROTENONEROTENONE IS OBTAINED FROM ROOTS OF A LEGUMINOUS PLANT Derris elliptica, D malaccensisAND CORK-BUSH,JEWEL VINE,TUBA PLANTIT IS SOLUBLE IN ORGANIC LIQUIDSIT IS A CONTACT POISONIT ATTECK NERVOUS SYSTEM
12. ROTENONECHEMICAL FORMULA OF ROTENONEIT WAS USED TO KILL CATTERPILLES WEEVILS FLEAS AND TO KILLFISHESAFTER DDT IT LOSTITS NEST
13. ROTENONEIT IS NOT VERY HARMFUL FOR HUMANS IT CAUSE VOMITING AND RETCHING
14. AZADIRACHTINTHIS INSECTICIDE IS OBTAIN FROM PARTS OF Azadirachta indica NEEM TREENEEM HAS INSECTS KILLING CHEMICALSCHEMICAL; FORMULA OF AZADIRACHTINIT IS VERY USEFUL AGAINSTSTORED GRAINS PESTSSitophilous oryzae,Rizopthera dominica
15. AZADIRACHTINIT IS ALSO USED AGAINST- VEGETABLE PESTSIT IS SAFE FOR HUMANS
16. ORGANOCHORINEDDT-DICHLORODIPHENYL TRICHLOROETHANEC14H9Cl5IT WAS EXTENSIVELY USED AFTER WORLD WAR-IIBUT DUE TO ITS HARMFUL EFFECTS ON ECOSYSTEM(BIOMAGNIFICATION)AND OTHER TOXIC EFFECTS IT WAS BANNED
17. CLORINATED INSECTICIDEALDRIN-C12H8Cl6USED AS DUST ,IT IS VERY POWERFUL POISONIT IS USED TO CONTROL-GRASSHOPPER,TERMITELOCUSTS ETC
18. ENDRINCHEMICAL STRUCTURE-C6H8Cl6OIT IS VERY TOXIC INSECTICIDE USED AGAINSTGRASSHOPPERSLEPIDOPTEROUS LARVAE(CATERPILLARS)COLEOPTEROUS INSECTS AND BUGS
19. ENDOSULFAN(THIODAN)CHEMICAL FORMULA C9H6Cl6O2SIT IS SYNTHETIC INSECTICIDEIT IS MAINLY USED AGAINST-APHIDSLEAF HOPPERSGRAM BORERBUGS AND CATERPILLARSMITES
20. ENDOSULFANNOT VERY TOXIC TO MAMMALS
21. ORGANOPHOSPHOROUSDICHLORVOS-KNOWN AS DDVPVERY FAST ACTING INSECTICIDEACT AS STOMACH,CONTACT POISON WITH FUMIGANT ACTION
22. DDVPIT IS USED AGAINSTSTORED GRAIN PESTMOSQUITOESFLIES,LEPIDOPTERNSMITES,LOCUSTS AND APHIDS
23. MALATHIONCHEMICAL NAME-VERY LONGTOXICITY-LD50-MAMMALS 479mg/KgSAFE INSECTICIDE USED AGAINSTSTORAGE PEST,VEGETABLE PEST
24. MALATHIONUNPLEASENT ODOUR
25. PARATHIONC10H14NO5PS
26. PARATHIONORAL TOXICITY-LD50RAT 3-6 mg/KgDermal toxicity – LD50 RAT 4-200 mg/kgIT ACT AS STOMACH CONTACT AND FUMIGANT POISONUSED AGAINST WIDE RANGE OF INSECTS AND MITES VERY TOXIC FOR MAN
27. CARBAMATE INSECTICIDECARBARYL-1 naphthyl N-methylcarbamate c12H4O2N
28. CARBARYLORAL TOXICITY-LD 50 RAT 400mg/kgDERMAL TOXICITY-LD50 RAT 500mg/kgNon specific insecticide USED AGAINST LICE,MITES ANDTICKS AND PESTS OF COTTON VEGETABLE
29. CARBOFURANC12H15NO3ORAL TOXIXITY-LD50 RAT-8.2-14mg/kgDermal toxicity-LD 50 RAT-10200mg/kg
30. CARBFURANUSED AGAINST-SUCKING PESTS,MITESAND ROOT INHABITINGPESTSEG-ROOT WEEVIL,CORN ROOT WORMFLEA,BEELTE LARVAE,MAGGOTS
31. FUMIGANTSGAS INSECTICIDES WHICH ENTER THE INSECT BODY THROUGH SPIRACLES AND KILL THEMEXAMPLES-CARBON TETRACHLORIDEHYDROGEN CYANIDEALUMINIUM PHOSPHATEMETHYL BROMIDEETHYLENE DICHLORIDE
32. ETHYLENE DICHLORIDECH2Cl.CH2Cl IT IS SLOW ACTING GAS KILLS INSECT IN 24-70 HRSSO IT IS USED WITH CCl4 IN RATIO 3:1 PART OFETDC AND CCl4 AND SPRAYED OVER CROP
33. HCNHCN IS INE OF THE MOST DEADLY FUMIGANTNEED HIGH PRECAUTIONS SO IT IS RELETIVLY LESS USED IN COMPARISON TO OTHER FUMIGANTS
34. METHYL BROMIDEMOST COMMONLY USED FUMIGANTDANGEROUS FOR MAMMALSSLOW ACTINGUSED FOR STOREDGRAIN PEST ANDNURSERIES ETC.
35. BANNED PESTCIDEALDRIN, METHY BROMIDE BHC, DDT, FERBAM, EPN, ALUMINIUM PHOSPHIDE , DAZOMET, DIAZINON CaCN,DIELDRIN , ENDRIN , PARATHION LINDANE MENAZON , HEPTACHLOR, NITROFENTCA , CAROFURAN 50% CAPTAFOL ,PARATHION
