World Pest Day is celebrated on June 6 every year, a multinational event created to raise the status of the pest management industry among the general public. We all are well acquainted with the bad consequences of agricultural pesticides on whole ecosystem. But a common question may arise- what if you have no other choices than using pesticides to protect your crops!! Is that all? Let's think! There certainly are lots of alternatives for controlling pest in your farm; eco-friendly methods of pest management! Here are some tips to make your farm eco-friendly:
1. Changing time of planting: Early sowing is found to be effective on reducing Shoot fly, white grub, aphid, podborer, gall midge and earhead bug. Seed rate and plant spacing also affect on pest population and are crop specific. Early planting also ensures disrupted synchrony 2. Disrupting the continuity of food sources: Disrupting food sources of pest can help to reduce pest infestation that can be achieved by following ways: a. Crop spacing: Since crop spacing vividly affect the plant growth as well as environment for pest survival and is crop specific, it is necessary to know what spacing can result in reduced pest population. b. Crop location: Fields situated nearby the unmanaged farms likely to be endowed with many pests should not be chosen for cultivation for it would be difficult to control pests. c. Crop rotation: Enriches soil fertility alongside interrupts pest life cycle when cereal -legume cycle is adopted i.e. host crop followed by non- host crop. 3. Tillage: Tillage exposes various life stages of pests so that predators feed and population can be reduced to some extent. E.g., Helicoverpa, root grubs, grasshoppers, etc. 4. Various cropping systems to divert pests from main crop: a. Trap cropping: Have you ever noticed marigold rows planted in Rice, potato and tomato fields? If yes, then it's for attracting the insects away from the main crop in order to save protected crops from pests damage. b. Intercropping: Different species of plants with different pest problems, non-competitive and of different fruiting habit can be intercropped. c. Barrier crops: Main crops can be surrounded by living barriers of tall plant species, they might include graminaceous species and banker crop, trap crop and Ecofeast crop or sacrifice crop. d. Mulches: Mulch reduces ability of pest to find their host plants due to visual interference or suicidal attraction to the sun- heated mulch. e. Push-pull poly cropping: Main crop is intercropped with repellant crops (push) and overall field is bordered with attractant crops(pull) for modifying the pest behaviour and manipulating pest population or any beneficial insects alongside protecting main crop. f. Plant nutrition and water management: Plant vigour also determines the intensity of plant to tolerate or resist their pests and it is found that slow release of Nitrogen from organic manure induces antixenosis, a defense mechanism of plant towards insects. Flooding or over head irrigation of field can flush and suppresses various life stages of insects. g. Sanitation: Field sanitation is the utmost factor for plant protection. Removal of crop residues, stalks and stubbles and alternate hosts of pests can aid in keeping your field out of pest as well as weed infestation reducing the pesticide or weedicide usage. h. Closed season: It refers to letting your field barren for some period just to break pest life cycle and this works best for monophagous pest. i. Physical intervention: This technique simply refers to the use of a device for controlling pest population, such as: hot water or hot air treatment, light traps, flame throwers, sticky traps, bird perches, cold storage and exposure to sunlight. Thus, let's make Agriculture eco-friendly, substituting the use of pesticides. Let's not fill our plates with pesticides. Green cheers!!

Hello Sandesh,
Crop spacing has a role in pest emergence as plant density provides required environment for pest survival and development.
Thanks for your comment and query.

Hello Asmita,
Thanks for sharing but i am confused do crop spacing influences the pest emergence directly?
