A pest may be defined as any organism that interferes with production of the crop.In spite of the general category of pests such as insects, diseases and weeds,there are many other types including nematodes, arthropods etc. What is Pest????? The level of damage, or potential damage, that is equal to the Cost of Control, the pest is considered to be at Economic Injury Level.
Why Pest Management in OF:-
Pest Management The How And Why Behind its Psychology and Working
With the help of one other is controlled
Management / control of rodents(Rats) Prepare concentrated sugar solution Dip cotton in that sugar solution Dry it in sun, and place the pieces of it in various part of the field When Rats consume it, it will hamper the Appetite and pathology of the rat Few rats dies few will suffer a serious pain The will leave the locality and so the colony Rats are social animals, lives in colony
What is Pest Management
CULTURAL METHODS Sanitation Tillage & Intercultivation Cultivar selection Time Of Sowing Plant Population Manures & Fertilizers Water Management Habitat Diversification
Behavioural Methods:-
Pheromones: chemical substances used by animals (mainly insects) to communicate Moths and bark beetles Kinds aggregation sexual - released by females to attract males Pheromone traps : -
Kairomone A Kairomone is a semiochemical mediating Inter-specific interaction emitted by an organism that benefits an individual of another species which receives it, without benefitting the emitter. Kairomone can be utilized as an ' attracticide ' to lure a pest species to a location containing pesticide.
Immunocontraception Vaccine that reduces fertility G lycoproteins (ZPG) inhibit egg fertilization Effective against wildlife populations
BIOLOGICAL PEST CONTROL There are many beneficial insects, birds; animals that help suppress the population of insect pest . Providing them home and habitat within your farm will greatly lessen Incidents of serious infestation. Bacteria, yeast and fungus (BYM ) that fight bad bacteria and fungus ; and damage the egg as well as adult insect-pests can be very helpful at low cost while renewable as they live and grow.
The natural agents control the pest through :
The biological agents
SOME ENEMIES OF INSECT PESTS
Chemical Methods Pesticide applications that have minimal risks associated with their use. Using the least amount of chemicals that will still be effective We Don’t use it in organic farming
Advantages Of PM
Disadvantages of PM
Pest management in organic farming 1. Pests of Rice Green leafhopper: Use resistant varieties like IR 50, CR 1009, Co 46, PTB 2 and PTB 18. Nursery should not be raised near the lamp posts Apply neem cake @ 12.5 kg/20 cent nursery as basal dose Maintain the water level at 2.5 cm for 3 days
2. Pests of Cotton Cotton aphid ( Aphis gossypii ) Release biocontrol agents viz., Coccinellid beetle Monochilus sexmaculatus and Coccinella septumpunctata and Aphelinus mali , A. flavipes . Predators - Phylloscopus tristis Monitor the nymphs and adults of early season sucking pests from the 14th day after sowing.
3. Pests of Sugarcane Shoot borer ( Chilo infuscatellus ) Resistant varieties: CO 312, CO 421, CO 661, CO 917 and CO 853 Planting – December – January escapes the incidence Intercrop: Daincha – low shoot borer incidence Earthing up – 30th day Trash mulching: 10 – 15 cm thickness o n 3 days after planting Ensure adequate moisture Remove and destroy dead hearts Tachinid parasite: Sturmiopsis inferens @ 125 gravid females
4. Pests of Sorghum Shootfly ( Atherigona varia soccata ) Use resistant varieties like Co-1, CSH 15R, Maldandi and Hagari . Sow the sorghum immediately after the receipt of monsoon rain to minimise the shoot fly damage. Use higher seed rate (12.5 kg/ha) and remove the shoot fly damaged seedlings at the time of thinning or raise nursery and transplant only healthy seedlings. Pull out plants showing dead hearts and destroy at the time of thinning. Set up hanging type of plastic fishmeal trap @ 12/ha till that is 30 days old. Release larval parasitoids viz., Tetrastichus nyemitavus , T. coimbaborensis , Callitula sp., Diaulinopsis sp., Pupal parasitoid - Cratalpiella sp. Predator - Abrolophus sp.
