General Instructions


An emulsifiable, narrow range, spray oil for the control of various pests of citrus, bananas, and other crops as specified in the Directions for Use table. Also for use in combination with other pesticides as specified on the Directions for Use table.





Different plant stresses can have cumulative effect. In general, follow good farming practice to minimise all other sources of plant stress. Avoid applying D-C-Tron Plus when environmental conditions elevate plant stress. AVOID spraying complex tank mixtures.

In particular DO NOT spray:

• when the soil is dry

• if trees are suffering from moisture stress

• if hot weather (> 35°C) is imminent or has occurred in the previous 4 days

• if the shade temperature exceeds 32°C

• in slow drying conditions


Since D-C-Tron Plus can be used as a herbicide adjuvant, any phytotoxic tendencies of other insecticides mixed with D-C-Tron Plus may be enhanced. Follow the label precautions on the other insecticides carefully and if in doubt about a certain mixture then test on a small area first before widespread use. 

D-C-Tron Plus sprays greater than 250 mL/100L water should not be applied for at least one month after spraying with sulphur or lime sulphur, as severe injury may occur, especially if the oil is applied in hot weather. 

DO NOT apply D-C-Tron Plus in combination with Propargite or within 4 weeks of a Propargite application. Adding spraying oils with Torque®1 Miticide/Insecticide can reduce the speed of action of Torque Miticide/Insecticide. Avoid applying Torque with D-C-Tron Plus where rapid speed of action is required.

DO NOT apply D-C-Tron Plus in combination with, or following a chlorothalonil application.

DO NOT use in combination with Supracide 400®2 Emulsifiable Concentrate Insecticide on mangoes after fruit set and while fruit is on the tree.

DO NOT use D-C-Tron Plus on mangoes during flowering or while fruit is on the tree.





D-C-Tron Plus is an effective insecticide when used alone to control light-moderate infestations of pests as indicated in the directions for use table.

When a range of D-C-Tron Plus rates is indicated, use the lower rate for light pest infestations and the high rate for moderate to heavy infestations, but only if

weather and tree conditions are favourable (see general instructions – precautions). Alternatively for heavy pressures, apply low rate 2-3 times at an interval of about a fortnight. DO NOT exceed maximum recommended annual dosage (see precautions section.) Time applications to target crawler stages of pests. Apply when trees are in good condition 7-10 days after rain or irrigation.

Apply sprays thoroughly to ensure complete coverage is achieved on both sides of susceptible leaves throughout whole canopy. The preferred type of sprayer for large trees is the oscillating boom with outrigger. As a general guide, 4m high trees with heavy infestations of armoured scale could require spray volumes from 10,000 to 14,000 L/ha, soft scales 8,000 to 10,000 L/ha, and mites 5,000 to 8,000 L/ha.

Adjust volume proportionally for tree size, planting density, target foliage (eg flush growth or whole canopy), canopy density and degree of infestation.

When pest pressure is moderate to heavy, and/or your spray equipment cannot achieve coverage comparable to an oscillating boom with outrigger, consider using D-C-Tron Plus in one of the mixtures indicated in the directions-for-use table. However, achieving thorough coverage should always be the aim no matter what mixture is used.


Precautions – Citrus

Refer to Precautions – General section above

DO NOT use rates higher than 0.6% in Queensland. Use high rate (1%) in southern Australia ONLY when all general spraying precautions are met (see PRECAUTIONS – General) and when pest pressure warrants. Always consider the low rate as the first spray option.

DO NOT apply when high rate of natural fruit drop is expected.

DO NOT apply within 4 weeks of harvest.

DO NOT apply Lorsban 500EC Insecticide in IPM programs. In SA, do not spray D-C-Tron Plus with Lorsban 500EC Insecticide if spraying in November/December.

DO NOT apply to Glen Retreat variety of mandarins. 

If petroleum spray oil is applied more than once from Spring to Autumn, either alone or in combination with other materials, the total strength of oil used

in commercial orchards should not exceed 3L of oil in Queensland, and 2L of oil in southern Australia.

DO NOT apply D-C-Tron Plus with Supracide 400 Emulsifiable Concentrate Insecticide to any citrus.

DO NOT apply D-C-Tron Plus in combination with Torque to Torque susceptible varieties of citrus such as tangerines, tangelos and some varieties of grapefruit.

DO NOT apply copper fungicides when slow drying conditions prevail or if it is likely to rain before spray is dry.

DO NOT use this product with copper fungicides on copper shy varieties.





High volume applications can be made from either a ground rig in a convenient volume of water eg. 200 to 500 L/ha, or from the air in at least 30 L/ha water. Low volume aerial application does not require any further dilution of the mixture indicated.

D-C-Tron Plus can be applied alone, with DMI fungicides or dithiocarbamate fungicides. When a range of oil rates is indicated, use the higher rate when weather conditions particularly favour disease development. Maintain good deleafing practices to reduce disease inoculum. Very old leaves, and leaves with advanced lesions should be removed, or infected parts of the leaf removed, prior to the application of DMI fungicides.


Sth Qld and NSW: Commence a protectant regime of fungicide sprays at the start of summer and continue until May. Alternate sprays according to an appropriate fungicide anti-resistance strategy using the following guidelines:

Apply DMIs at least twice consecutively and to a maximum of 5 per season at 21 to 28 day intervals.

Apply Dithane Rainshield Fungicide or Penncozeb 750DF Fungicide sprays at 3 to 4 week intervals from the ground and at 7–10 day intervals from the air.


Nth Qld, WA and NT: Alternate fungicides according to an appropriate fungicide anti-resistance strategy. Use dithiocarbamates as major component of

strategy. Apply sprays at 10-14 day intervals during all periods favouring disease development. Extend this to 21 or 28 days during drier, cooler periods. Apply oil with all fungicides. Apply DMIs a maximum of 6 times per year and no more than twice consectively.

Do not apply DMIs from July-November.

In Nth Qld only, apply Dithane Rainshield Fungicide or Penncozeb 750DF Fungicide sprays at 2-week intervals during the wet season, 3 weeks after this, and 4 or 5 weeks during the dry season. Prior to the next wet season return to 3-week intervals. Folicur®3 430SC Fungicide is approved for use in banana plantations interplanted with avocados.


Precautions – Bananas

Refer to Precautions – General section above

DO NOT apply D-C-Tron Plus directly to unprotected fruit. Cover all bunches prior to spraying D-C-Tron Plus at high rates (>5 L/ha) from ground. If a spray directly to fruit is warranted DO NOT use D-C-Tron Plus. Spray to a maximum of 100L oil/ha per season. There are certain conditions when the surface of recently emerged fruit is particularly prone to marking damage from spray applications of DMI or dithiocarbamate fungicides. Refer to DMI or dithiocarbamate labels for precautions when spraying directly onto fruit.


Dormant Fruit Trees – Pome Fruit, Stone Fruit and Grapevines


Ensure thorough coverage of limbs and branches.



Refer to Precautions – General section above

DO NOT apply to prunes or other known soil sensitive varieties.

DO NOT apply during the early dormant period.

Very occasionally Vertimec®2 Miticide/Insecticide plus summer oil has caused slight fruit russetting on some sensitive pear varieties such as Anjou. DO NOT

apply Vertimec Miticide/Insecticide to apples or pears before or after applications of Delan®1 or Captan. DO NOT make Vertimec Miticide/Insecticide plus D-C-Tron Plus applications:

• when the temperature exceeds 28°C or are expected to exceed 28°C within 48 hours after application

• under poor or slow drying conditions or

• with equipment that may leave large droplets on fruit after application

DO NOT apply D-C-TRON PLUS to pome fruit following Delan sprays or within 14 days, before or after, Captan sprays.


Mixing Instructions


Pour the required amount of water into the mixing tank then add the D-C-Tron Plus and agitate well. When using in combination with other pesticides, mix the

pesticide first (except Carbaryl) according to the manufacturers instructions, then add the D-C-Tron Plus. For specific mixing instructions when using D-C-Tron Plus with other insecticides, refer to the other insecticide label. 

Consult insecticide/fungicide labels for minimum spray volumes per hectare.

Follow appropriate resistance management strategies recommended on insecticide/fungicide labels.

Ensure that oil-water mixtures held in spray tanks or containers during application are continually and effectively agitated or stirred to prevent the oil separating from the water.


Protection of wildlife, fish, crustaceans and environment


Do not contaminate streams, rivers or waterways with chemical or used container.


Storage and Disposal


Store in the original container, tightly closed in a safe well-ventilated area, as cool as possible. Do not store for prolonged periods in direct sunlight. This container can be recycled if it is clean, dry, free of visible residues and has the drumMUSTER logo visible. Triple rinse container for disposal. Dispose of rinsate by adding it to the spray tank. DO NOT dispose of undiluted chemical on site. Wash outside of the container and the cap.

Store cleaned container in a sheltered place with cap removed. It will then be acceptable for recycling at any drumMUSTER collection point or similar container management program site.
