 Biochemicals in Insect control ...


 In view of the dangers posed by the rampant use of pesticides in vegetable cultivation, agronomists have come up with some biological control methods to control the pests without harming the environment and consumers.


  This method uses microorganisms that cause disease and degeneration of crop-expecting insects.  Virus-based biochemical NPV  The solvent (500 LEDs) is recommended for the control of herbivorous peanut mite and tobacco leafhopper.


 Bt in bacterial-based biochemicals.  Formulations (1 to 2 ml per liter of water) control the aphid, the tobacco leafhopper, and the nominal aphid.


 Bavaria, Metarhizium, and Virgicellium are prominent fungal-based biochemicals.


 These are available in water-soluble powder form.


 These include the control of caterpillars that feed on the leaves of Bavaria baciana.

  Juice in crop plants are addictive for the control of sucking insects.


  These biochemicals are applied at a rate of 5 g per liter of water.  Spray together at the rate of.


  In the prevention of pests ...



  Biochemicals are also available in pest control.


 Trichoderma viridis fungus is effective in preventing damping off rot in vegetables.


  Harmful fungi in the soil can be controlled if 4-5 kg ​​of this fungus powder is mixed with 100 kg of well manure and not sprayed on the field during plowing.


 The powder of this fungus is 10 g per kg of seed.  Seed treatment at the rate of one can significantly reduce root rot




Although the use of biochemicals is beneficial in vegetable cultivation, their storage capacity is only 6 months to less than 1 year.


 Many companies are selling these products in the market without following the proper quality standards as the facilities for testing their quality are limited.


  That is why the expected results in the farmer fields are not coming as popular as expected.  To make the best use of these drugs, farmers must purchase a drug that is manufactured by a reputable organization or agricultural research firm.


  The date of manufacture, last date of use and precautions to be used on the packet should be carefully considered at the time of purchase.


 It is advisable for farmers not to buy medicines that are nearing the deadline.


 Parasites:


 Scientists have also made available parasites that destroy the eggs of insects that destroy vegetable crops.

 The most prominent of these is the trichogramma parasite, which infests insects' eggs and destroys them.


  These are available in the market as tricho cards, which can be arranged at the base of the crop leaves at the rate of 4 tricho cards per acre.


 Consumption of chemicals: -


 Even if the above mentioned methods are followed in vegetable cultivation, in case of crop damage due to pest infestation, the following pesticides should be sprayed in one liter of water as per the expert advice for effective control.


 Insect Prevention: -


  Leaf-eating insects:


 Chlorpyrifos 2.5 ml.  (Profenofos 2 ml / amomectin benzoate 0.4 g.


 Stem and stem borers: -

  Emamectin benzoate 0.4 g.  / Thiodicorch (larvin) -2 g.  !  Rhinoxifer (corazine) -0.3 ml.  / Pubem diamide (0.5 ml)


 Juice sucking worms: -


  Roger 2 m.  Lee.  / Imidacloprid 0.4 ml.  / Thiomethoxam 0.3 g.  Eczema mites: Roger 2 m.  Lee.  / Pipronil 2 m.  Lee.  |  Spinosad 0.3 ml.  / Thiomethoxam 0.3 g, black or mites: 3 g of water-soluble sulfur.  / Proper gait (ohmite) 2 m.  Lee.  / Spiromesifin (Oberon -1 ml /.

 Chlor Penfire (Intrepid) 2ml


 Nematodes:


  Carbopuran pellets 10 kg / acre Pest control Pest control: Diethane M-45 (3 g) / Carbendazim 1 g.  / Coffer oxychloride 3 g.  / Diphenaconazole 0.5 ml.  Green rot: Diethane M-45 (3 g) or chlorothalonil 2 g.  Or ajaxisobin (Amistar) -1 ml.  Or propineb 2 grams


 Gray rot: -


  3 g of water-soluble sulfur.  Or TrideMarch 1 m.  Lee.  Or hexaconazole 2 ml.  Or Dinocap 2 ml.  Or 1 gram of butanil in mic.


  Dryness: -


 Copper oxychloride (3 g / l) solution should be applied at the beginning of the plant.  Bacterial pests: (Streptocycline 0.2 g. + Copper oxychloride 3 g.


  Virus rot: -

 There is no prescriptive drug that will stop the flow of emotions, though their effects can be curtailed.  Farmers should show the crop-borne pest or pests to the concerned officer and use the recommended drugs and dosages as recommended.


  In some cases 200 g per acre.  Or 600 m.  Lee.  If the shop recommends they 250 g.  Or 500 m.  Lee.  It is advised that it is okay to carry the whole pitch.


 But using more or less than recommended will not only be costly but will also make pests and insects more resistant to these drugs.  These can be difficult to prevent in the future
