Rodent damage assayed in and around B-block building, trees, road sides in different locations at Muhammad Nawaz Sharif University of Agriculture. Chemical control (Klerat®Waxblocks). Results showed the damage percentages were 66.6 % B-block, 89.35 % in Citrus. The results of chemical control showed that Klerat®Waxblocks bait was more effective. Klerat®Waxblocks achieved 87.26 % population reduction of rats in Citrus. Concerning building premises, 79.7 % population reduction of rats.

MNS- University of Agriculture, Multan is the most sustainable university of Pakistan, though being a young university, it has not only achievements in Pakistan, also achieved a global rank in 2022.

Rodenticides are pesticides that kill rodents. All rodenticides can be toxic when eaten, Rodenticides may be coagulants, or anticoagulants.

Citrus are important commodities and non-traditional crops that can be used for both local consumption and export. This is due to the citrus characterized by their containment of many foodstuffs, vitamins and mineral salts. Citrus are the important economic crop in Pakistan so it is necessary to control pests harmful to Citrus.

Rodents considered as one the most important pest in not only in Pakistan all over the World. That caused great economic loss to farmers (damage the growing crops, stored products, poultry and animals farm).

Rat damage to certain crops and density of Arvicanthis niloticus in Fayoum Governorate (Asran, et al., 1991). Khan et al., (2009) recorded that control of rodent damage to groundnuts in the postwar plateau region of Pakistan with zinc phosphide. (Metwally, et al., 2011) recorded that use of some mechanical and chemical control methods to control rodent species in some field crops and date palm trees in experimental farm of Al- Azhar University in Assuit. Desoky, (2013) reported that zinc phosphide as chemical control and handing destroy of burrow, deep irrigation and traps as mechanical control to control Arvicanthis niloticus in Sohag Governorate. The present work aims to:

Rodent damage assessment on Citrus and buildings.

Different Places were chosen from different locations at MNS-UAM as new reclaimed lands.

The fruit crop was Citrus and the building was B-Block.

Assessment of damage in Citrus and Building:

Initially all the burrows were closed and counted as well. After somedays visited the area/field again and counted the freshly opened burrows in, around the building and in the field.

Population Estimation = Initial active burrows - post active burrows        *100

Name                           Klerat®Waxblocks

Composition:               0.005% Brodifacoum

Formulation:                 Block Bait

Mode of action:            Ingestion

Dosage:                        Single Feed

Klerat®Waxblocks are ideal for use in baiting rodent burrows, buildings, grain and food stores, as well as wet environments, including sewers and drains. The central hole in each block allows them to be easily secured in baiting stations and prevents rodents carrying them away.

Appropriate numbers of bait stations were installed at different locations were freshly opened burrows were found. Bait station were typically a 4 inches sewerage pipe of Plastic. Initially Bait stations were installed with a food source in order to attract the rodents towards bait station. When the whole food material was eaten away then we installed

Rodent damage assessment to Citrus and MNS-UAM:

Results showed that the average damage percentage caused by Rattus rattus on Citrus were very high, the percentage was 89.35%. While it was high in Building premises, the percentage was 66.6. However, it was very low in the fields where baits were installed. 

 achieved 87.26 % population reduction of rats in Citrus. Concerning building premises, 79.7 % population reduction of rats.

Rodent damage Citrus may be due to neglect of the farmer, non-clean around the trees and not demolition of rat burrows. These results agree with Asran, et al., 1985 and Ahmed 2007 the damage in crops was due to density of rats.

 bait against R. rattus achieved 87.26 % population reduction of rats and the consumed amount of bait was reduce from 25 wax blocks to 6 wax blocks in Citrus. While the population redaction of rats in building was 79.7 % and the consumed amount of bait decreased from 87 wax blocks to 13 wax blocks.

Brodifacoum anticoagulant bait caused 87.26 % rat population reduction with decline consumed from 25 wax blocks to 6 in Citrus. While it caused 79.9 % with decrease amount consumed from 87 wax blocks to 13 wax blocks.

From the previous results, Brodifacoum anticoagulant bait was more effective bait against rats, whereas it caused high population reduction with high consumed in the Citrus and buildings. Also, gave good results as an acute poison.

Population reduction of rats in date palm and orange trees was declined may be due to toxic effect of Brodifacoum bait. Rodent controlled in cane field by some rodenticides as zinc phosphide, brodifacoum, coumatetralyl and bromethalin. found that decrease in population reduction of rats by using some rodenticide compound. The reduction of rodents was due to using two compounds, bromadiolone and zinc phosphide. The effect of warfarin, dopaquinone and chlorophacinone are very effective against rodent in Pakistan. The reduction of rodent in all crops due to toxic effect of bromadiolone and chlorophacinone (Ahmed, 2017).
