Al.P.Tablets (Aluminnium Phosphide Tablets)

Al.P.Tablets (Aluminnium Phosphide Tablets)  

  • In the plugged burrows use Aluminium Phosphide tablets 0.6g@ 2 pellets per burrow only by skilled person.
  • Should be placed deep in the burrow with the help of metal rod.
  • Avoid usage of pellets in fire places and during rainfall.

Bait Placement

Bait Placement

  • Bait should be placed in rodent burrows or bait stations only.
  • In rodent burrows- place 10-15g bait packeted in paper (to avoid loss) deep in burrow and close all the exit opening of burrows.
  • In Bait Stations – Arrange different bait stations like traditionally made coconut husk, pot, bamboo bait stations and fill 50-60g bait in it and monitor daily later clean and refill the bait stations after the rodents consumed the total bait.
  • Spoiled and unconsumed bait should be cleaned from bait station and burry in soil.
  • For effective utilization of baits arrange PVC pipe and cement made permanent bait stations @ 6-8/acre.

Zinc Phosphide and Bromodiolone

Zinc Phosphide and Bromodiolone

Zinc Phosphide  

  • After consuming the zinc phosphide bait, the rodent will die within one day due to stomach burning, hence the other rodents develop bait shyness for a period of 2-3 months depending on species and bait dose. So, this poison bait should be used only once in a crop season where there is high rodent infestation.
  • Prebaiting for 3 days without chemical is necessary.

Bromodiolone

  • After consuming the Bromodiolone bait, the rodent will die slowly from 4-6days due to non clotting of blood.
  • This death seems to be normal hence no bait shyness will develop
  • No pre baiting needed
  • Can be used 3-4 times in a season

  • Cleaning of bunds and optimizing the bund size.

Physical methods:

The Physical methods for Rodent Management involve

  • live catch of rodents,
  • killing and burying in soil.

Mechanical methods:

The mechanical methods of rodent management include:

  • Installing rodent traps @ 15-20/acre to control migrating rodents.

Introduction to Rodent Management

Introduction to Rodent Management

  • In Paddy, besides pests and diseases rodents are also causing severe damage pertaining to yield losses ranging from 0.44 to 90 percent.
  • In some severe infested fields due to rodents even 95 percent yield loss also recorded where farmers abounded the crop without harvesting.  
  • Out of 12 sps of field damaging Rodents identified, only 2 sps of rodents cause damage to rice,
  • a) The Lesser Bandicoot-Bandicota bengalensis
  • b) The Field Mouse ,Mus booduga
  • Out of these two, the Bandicoot Rodent has spread all through the country and has capacity of breeding throughout the year and in abnormal reproduction increases their litter size double the home range (12-22 young ones in one delivery).
  • If this rodent is managed the damage of rodents to paddy will be controlled up to 90%.
  • The field mouse causes only 10% damage.

False Smut

False Smut

Symptoms of False Smut

1. Symptoms of the false smut will be seen only after flowering.

2. The pathogen, Ustilaginoidea virens, grows in the ovary and transforms it into large, yellowish and velvety green balls, which become greatly enlarged at later stage.

3. The spore balls are covered by a membrane in the early stages, which bursts on further growth and the loose velvety pseudomorphs become visible.

Control of False Smut

1. Destruction of straw and stubble from infected plants reduce the disease.

2. Applying Captan, Captafol, Fentin Hydroxide, and Mancozeb can inhibit conidial germination.

3. Fungicides, Propiconazole, Copper Oxychloride, Mancozeb and Chlorothalonil effectively reduce the incidence of the disease.

Control of Sheath Rot

Control of Sheath Rot:

1. Removal of infected stubbles after harvest and adopting optimum plant spacing can reduce the disease.

2. Application of potash at tillering stage is also recommended.

3. Foliar spray of calcium sulphate and zinc sulphate was found to control sheath rot.

4. Apply Carbendazim 50WP@ 1g/l. Other products like Thiophanate-Methyl, Ediphenphos, Hexaconazole, Propiconazole and Mancozeb, also useful in reducing sheath rot.
