6 GENERAL DESCRIPTION:

Spray.Seed started the minimum tillage revolution

It is a broad spectrum, contact herbicide that desiccates plants. The major uses are for controlling small, annual weeds before planting crops, directed sprays in perennial crops and as a pre harvest desiccant for crops such as potatoes and canola. It has no soil activity because it is bound to clays in the soil very strongly. It presents little hazard to the environment because the strong binding to clays prevents the herbicide entering the soil solution to leach or affect organisms. Spray.Seed is toxic to animals and care should taken to avoid exposure. The greatest exposure risk is via inhalation of spray mist and consequently it is not registered for use in misters or for normal aerial application.

7 APPLICATION METHODS AND TIPS:

Protective clothing should be warn when using Spray.Seed. A respirator is recommended.

Spray.Seed is usually applied in water as a broadcast application through hydraulic nozzles or as a directed spray using hand held equipment.

Surfactants and oils often improve weed control but it is usually more economical to increase the rate of Spray.Seed.

Under stressed conditions plants become more tolerant to Spray.Seed.

Dust on the leaves of plants will deactivate Spray.Seed resulting in poor control.

Spraying in the evening, at night or on dull overcast days will improve the translocation of Spray.Seed and often improve weed control.

Conventional fan nozzles are better than air inducted or Turbo Drop nozzles for Spray.Seed application.

Efficiacy is better under high humidity or low delta T conditions.

Suggested procedure for crop establishment:

Graze stubble to break it up and reduce bulk.

Graze weeds from germination to prevent the formation of large root systems and provide hoof cultivation to encourage seeds to germinate. Avoid allowing weeds to grow then grazing off before spraying.

Remove stock 2-3 days before spraying and preferably wait for a rain to wash dust off leaves.

Spray with a boom spray.

Cultivate 1-7 days after spraying. In dense weed stands cultivation may be more effective after 3 days when roots have started to die.

Sow soon after cultivation.

8 WEATHER:

Rainfast in 1 hour.

Frost effects: Frosts before spraying may reduce plant growth result in poorer weed control. Frosts more than an hour or two after spraying have little effect on herbicide activity. The effectiveness of night applications may be reduced by frosts before sunrise.

Wind:

Inversions: Avoid spraying during inversion conditions.

Temperature: Low temperatures may reduce weed kill by 10-20%.

Delta T and relative humidity: Avoid application when Delta T is greater than

Soil moisture at application:

9 ADJUVANTS:

Wetting agents: Spray.Seed contains a non ionic wetter sufficient for spray volumes up to 100 L/ha. Add 200 mL non ionic wetting agent for each additional 100 L/ha of spray volume

Spray oils: Use oils if companion herbicides require them.

10 WATER QUALITY:

Hard water:

Salty water: Salt has little effect on efficacy.

Colloids: Colloids and clay will reduce the efficacy

pH: Little effect.

Tank life: Several weeks in clean water.

Saline Water - Nil if water is free from clay particles.

Soil Colloids - Can affect application but normally not a problem. As a rule of thumb - if a coin can be seen on the bottom of a 10 litre bucket full of water then little loss of activity is seen. Dirty water can be settled with alum or lime as described in the HerbiGuide Information/Water Quality section.

Spray.Seed is absorbed onto clay particles, reducing the amount available to control weeds.

Use water that is free from clay, silt and algae.

11 COMPATIBILITY:

Non ionic surfactants and crop oils increase absorption of herbicide and often improve the degree of weed control.

Triazine herbicides are often synergistic with Spray.Seed. This may be due to the photosynthetic inhibiting properties of triazines resulting in better translocation of Spray.Seed from its point of contact. Spray.Seed is usually antagonistic with translocated herbicides. The fast action of Spray.Seed kills the tissue before other herbicides have moved. However, at low use rates and on plants that have some tolerance to Spray.Seed there are useful mixtures. In particular, metsulfuron(Ally) and dicamba are commonly used as a tank mix to improve the control of clover.

Not all formulations of diuron, simazine and atrazine are compatible with Spray.Seed.

Zinc sulphate and copper sulphate are antagonistic with Spray.Seed. This is caused by ionic reactions and results in a significant loss of efficacy. Manganese sulphate and calcium carbonate (lime) have lesser effects.

12 EQUIPMENT:

Boom sprays:

Carrier volume:

50 - 100 L/ha for small 2-5 leaf well separated plants up to 2 cm tall or wide.

100- 150 L/ha for 5 leaf to early tillering or rosette plants up to 5 cm tall or wide.

150 - 200 L/ha for dense or tall weeds swards up to 10 cm tall

For dense and or tall swards more than 10 cm tall use a split application at 150 L/ha.

Nozzles: Flat fan. 110 degrees. Double overlap.

Pressure: 150-400 kPa.

13 SPRAYER DECONTAMINATION:

Clean Up:

Clean soon after spraying to reduce the risk of forming dried deposits that may be difficult to remove.

Remove filters and clean separately. Triple rinse with water or water plus 0.25% wetting agent and run through boom.

Decontamination:

Remove filters and clean separately.

Rinse with water and drain.

Quarter fill the tank with an alkali detergent (eg 500 mL or g of Drive, Dynamo, Omo, or Surf per 100 L water) and circulate for at least 15 minutes then run through boom. Rinse twice with water.

Chlorine based cleaners are not recommended.

14 HERBICIDE RESISTANCE:

Plant populations tolerant to Spray.Seed are expected to occur naturally after repeated applications.

15 REPLANTING INTERVALS:

CropTime
All1 day

In heavy stubble situations wait a few days or for a rain before planting as transfer of Spray.Seed to emerging crop is possible.

16 WITHHOLDING PERIODS:

CropTypeTime
AllGrazing1 day
AllGrazing for horses7 days
AllHarvestNot required

17 RE-ENTRY PERIOD:

Wear protective clothing if in contact with the crop before the spray has dried.

18 PROTECTIVE CLOTHING:

Overalls, boots and washable hat. Use gloves and face shield when handling the concentrate.

Avoid contact with broken skin.

Avoid mist and use a mist mask if exposed while spraying.

19 SOIL:

Soil texture: No effect.

Soil pH: No effect.

Soil organic matter: No effect.

20 MODE OF ACTION:

Spray.Seed is absorbed by the leaves of plants. It is not translocated at high light intensities because the leaf tissue is killed very quickly. Under low light or dark conditions Spray.Seed acts more slowly and may move some distance from the point of application. It forms a stable free radical which interferes with the electron transport process. The reduction of carbon dioxide in the photosynthetic pathway is inhibited. This results in the production of superoxide radicals which attack unsaturated fatty acids. This causes degradation of cell membranes and loss of water resulting in desiccation of the plant.

It is a group L herbicide categorised as inhibitors of photosynthesis at photosystem 1.

20 MODE OF ACTION:

Uptake and translocation:

Contact herbicide. Little translocation. There may be some passive movement with night applications.

Physiological effects:

Membrane breakdown.

Residual Life and Breakdown:

No residual activity in soil. Binds strongly to clays.

21 SELECTIVITY:

Crop tolerance:

Burns most plants off but large plants and perennials may recover.

Varietal sensitivities:

Effect on Clover Species:

High rates kill clover. Low rates are tolerated.

Effect on Medic Species:

High rates kill clover. Low rates are tolerated.

Effect on Lucerne:

Burn top growth and may kill seedlings. Established plants generally survived especially if they have been grazed heavily or cut before spraying.

Effect on Native Plants:

Burns off top growth but most established perennial natives will survive. High rates kill most seedlings.

22 DISEASE AND INSECT EFFECTS:

No particular effects.

23 PLANT SYMPTOMS:

Spray.Seed is rapidly absorbed and stops plant growth quickly. The plants begin to wilt within hours of application. They usually turn brown within a day or two and die. Plants exposed to Spray.Seed drift often show spots of dead tissue where individual droplets of spray have contacted the leaf. Perennial species or annual species with large root reserves may loose all the leaves that have been sprayed but regrow new ones to survive.
