Fruit and Nut Tree Orchards (Dormant)

  • VOLES & WHITE FOOTED MICE
    • Product: ZP AG Pellets & Short Pellets
      • USE RESTRICTIONS: For control of Meadow, Prairie, Pine, California, Oregon, Mountain, and Townsend’s Voles (Microtus spp.) and White-footed Mouse (Peromyscus leucopus)  in pome fruit (apple, pear), stone fruit (peach, cherry, apricot, plum, prune, nectarine) and nut tree orchards (almonds, walnuts, pistachios, pecans, filberts).  Apply only after fall harvest (including drops), before new spring growth and when no rain or snow is expected for three consecutive days.  Do not graze animals in treated areas.

      • HAND BAITING: Place bait near bases of each infested tree at 2-4 locations, either on surface trails or at mouth of holes leading to underground burrow systems.  Cover bait artificially (e.g., mats, boards) or by pulling overhanging grass over bait. Do not allow bait to be exposed on bare ground. Do not disturb the runway system.  Apply teaspoon amount (4 grams) per placement, 2 - 3 lb/A (0.04 - 0.06 lb ai/A).

      • TRAILBUILDER: Set equipment to drop one teaspoon quantity of bait (4 grams) at 4-5 foot intervals in the artificial trail, made by the machine, just inside the drop line on both sides of the trees.  Apply at the rate of 2 - 3 lb/A (0.04 - 0.06 lb ai/A).

      • GROUND BROADCAST: Broadcast evenly by cyclone seeder or by hand.  Concentrate in areas with heaviest vegetative cover.  Do not broadcast on bare ground.  Apply at the rate of 6 - 10 lb/A (0.12 - 0.2 lb ai/A).

      • AERIAL BROADCAST: Do not broadcast on bare ground.  Apply at the rate of 6 - 10 lb/A (0.12 - 0.2 lb ai/A).
    • Product: ZP AG Oats & Squirrel Oats
      • USE RESTRICTIONS: For control of meadow voles, prairie voles, pine voles, California voles, long-tailed voles, Oregon voles, mountain voles, Townsend's voles (Microtus spp.) and white-footed mice in orchards and groves.  Apply bait after harvest while the orchard or grove is in a non-bearing phase.

      • HAND BAITING: Near the base of each infested tree, place teaspoonful quantities of bait at 2-4 locations, either on surface trails or at the mouth of holes leading to underground burrow systems.  Cover bait artificially (e.g., mats, boards) or by pulling overhanging grass back into place.  Do not allow bait to be exposed on bare ground.  Do not disturb the runway system.  Bait at the rate of 2-3 lbs. per acre of infested trees.

      • TRAILBUILDER: Set equipment to drop one teaspoon quantity (4 grams) of bait at 4-5 foot intervals in the artificial trail, made by the machine,  just inside the drop line on both sides of the trees.  Apply  bait at the rate of 2-3 pounds per acre of infested trees..

      • BROADCAST BAITING: Under infested trees broadcast bait evenly by cyclone seeder or by hand. Wear rubber gloves during hand-broadcast operations.  Concentrate baiting in the areas with the heaviest vegetative cover.  Do not broadcast on bare ground or growing crops.  Apply bait at rates from 6-10 lbs. per  treated acre.

      • AERIAL APPLICATION: Broadcast bait at a rate of 6-10 lbs. per acre.  Do not apply on bare ground or growing crops.

  • GROUND SQUIRRELS
    • Product: ZP AG Pellets & Short Pellets
      • USE RESTRICTIONS:  For control of California ground squirrels (Spermophilus beecheyi) and Richardson’s ground squirrels (S. richardii) in pome fruit (apple, pear), stone fruit (peach, cherry, apricot, plum, prune, nectarine) and nut tree orchards (almonds, walnuts, pistachios, pecans, filberts).  Apply only after fall harvest (including drops), before new spring growth and when no rain or snow is expected for three consecutive days.  Do not graze animals in treated areas.

      • PREBAITING (Mandatory):  Prebait with a 50/50 mixture of ground corn and wheat to enhance acceptance by California and Richardson’s ground squirrels.  Apply the prebait mixture at 6 lbs per acre 1-2 days prior to using ZP AG Pellets.

      • HANDBAITING:  Apply 4 grams (one teaspoon) of bait on the ground near active burrows.

      • BAITING:  Treat once during treatment period.  Broadcast bait using hand or ground-driven dispensing devices not to exceed 6 lbs per acre (0.12 lb ai/A)Dispose of excess bait from application equipment by burial.
    • Product: ZP AG Oats & Squirrel Oats
      • USE RESTRICTIONS: For control of California Ground Squirrels (Spermophilus beecheyi) and Richardson’s Ground Squirrels (Spermophilus richardii) in orchards and groves.  Apply bait after harvest while the orchard and grove is in a non-bearing phase.

      • PREBAITING: Prebaiting with 6 lbs. of untreated steamed crimped oats per acre one or two days prior to using ZP AG Oats is likely to enhance bait acceptance by California and Richardson’s ground squirrels.

      • HANDBAITING:  Apply one teaspoon (4 grams) of bait on the ground near active burrows.

      • BAITING: Treat only once during treatment period.  Broadcast bait using  hand or ground-driven dispensing devices not to exceed 6 lbs. per acre. Wear rubber gloves during hand–broadcast operations.  Dispose of excess bait from application equipment by burial.

  • POCKET GOPHERS
    • Product: ZP AG Pellets & Short Pellets
      • USE RESTRICTIONS: For control of plains pocket gophers (Geomys bursarius), southeastern pocket gophers (G. pinetis), yellow-faced pocket gophers (Pappogeomys castanops) and pocket gophers (Thomomys spp.) pome fruit (apple, pear), stone fruit (peach, cherry, apricot, plum, prune, nectarine) and nut tree orchards (almonds, walnuts, pistachios, pecans, filberts).  Bait must be applied directly into pocket gopher's underground burrow systems or into underground tunnels created by burrow-builder machines.  Do not apply bait above ground.  Apply only after fall harvest (including drops), before new spring growth and when no rain or snow is expected for three consecutive days.  Do not graze animals in treated areas.

      • HAND BAITING: Follow the directions indicated below to locate and treat pocket gophers’ burrow systems.
        Locating Underground Runways: Use a specially designed gopher probe, a metal rod, a strong smooth stick, or other suitable implement to probe the ground 10 to 15 inches away from fan-shaped gopher mounds.  Begin probing on the flat side of the fan.  When the main runway has been entered, the probe will drop about 2 inches due to decreased resistance from soil.
        Applying Bait to Runways: Using a long-handled spoon or mechanical probe, drop one teaspoon (4 grams) of bait into the main runway at each baited point.  Cover the opening with sod, a rock, or soil to exclude light.  Take care not to cover bait with soil.  Depending upon mound density, make two to five bait placements per burrow system.  Recover and bury all spilled bait.  Applied in this manner, one pound of bait will treat one to eight acres, depending upon the number of pocket gopher burrow systems present.

      • BURROW BUILDER: Follow manufacturer’s instructions for the type of equipment used.  Calibrate equipment to drop a teaspoon quantity (4 grams) of bait at 4-5 foot intervals in the artificial burrow made by the machine.  Apply at a rate of 2-3 lbs. of bait per acre (0.04 – 06 lb ai/A). Pick up and disposal of all spilled bait according to “Pesticide Disposal” instructions.
