Electronic Bird Repellent & Control Devices

 

In the early days of Pestman Bird Repellent (PBR) application, the crop growth showed a positive trend.

  • Some effects were observed in the areas treated by Pestman Bird Repellent (PBR).
  • In the areas with very high Quelea quelea infestation area, the rice field treated with low dose of 750ml PRB/ha had been obviously damaged by the birds, and lots of rice ears had been eaten by the birds.
  • In the areas with very high Quelea quelea infestation area, the recommended dose is 1 ltr PBR/ha and 1.5 ltrs PBR/ha. The bird damage was very few in the treatedfields, and the rice ears are very full.

 

 

Does another Bird Repellent (Code : AA30) work or not ?

  • Unlike the areas treated by Pestman Bird Repellent (Code : PBR), the birds were not driven away in the fields treated by bird repellent (Code : AA30), so this bird repellent was completely ineffective on Quelea quelea in the rice fields.
  • The damage in the rice fileds treated by bird repellent (Code : AA30) are obviously, but the damage is lower than untreated fields by bird repellent.

 

 

  • With high Quelea quelea infestation area treated by bird repellent (Code : AA30), the rice are obviously damaged by Quelea quelea, but in very few cases the birds will damage the whole rice ears.

 

Conclusion: After calculating the rice yields, we found that Pestman bird repellent is really effective on repelling Quelea quelea in rice fields, while bird repellent (Code : AA30) is not. Pestman Bird Repellent (Code: PBR) is an excellent bird repellent product against Quelea quelea in the rice fields.
