Anonim

"Callisto" - a specialized herbicide. It is used for processing corn fields. Produces a new means of protection company Syngenta (Switzerland). Its products (fungicides, insecticides, herbicides) are used by farmers, agro-industrial enterprises.

Composition, form of release and purpose of the drug "Callisto"

The basis of the drug is mesotrione. It is a synthetic analogue of the natural herbicide produced by Callistemon citrunus ornamental shrubs. The toxic substances that this plant variety emits inhibit the development and growth of crops growing nearby.

The drug is produced in liquid form - SC (suspension concentrate). Packed in a 5 liter container. The concentration of mesotrione in the herbicide is 480 g/l. Action spectrum "Callisto":

  • perennial and annual broadleaf weeds growing in a corn field;
  • dicotyledonous annual weeds growing on a poppy field.

Mechanism of herbicide action

Treatment with a selective, systemic, post-emergence herbicide does not harm corn. They can be sprayed on the crop in the 8th leaf phase. Due to the mild effect of the drug on young plants, weed control work is carried out in a timely manner. The tool belongs to the class of triketones.

The active substance that forms the basis of Callisto has a systemic effect on weeds. During the day, 80% of the solution penetrates into plant tissues. Results are visible after 1-2 days, signs of herbicide action:

  • tissue discoloration at growing points;
  • the entire above-ground part becomes light;
  • fabrics die.

Weeds die completely within 1-2 weeks.

Good and bad sides

Callisto herbal preparation has a number of advantages. It is used in tank mixes. It kills weeds that other herbicides don't work on. Treatments are carried out at different stages of development of corn and weeds. The use of "Callisto" eliminates the re-emergence of weeds:

  • bindweed;
  • thistle;
  • rope;
  • ambrosia;
  • other cereals, dicotyledonous weeds.

In conditions of heavy infestation, Callisto cannot cope with all types of weeds. It is used in combination with other means. It works most effectively with Milagro. Their mixture kills 90-95% of weeds in a corn field.

Working fluid consumption rates

"Callisto" has a prolonged effect. During the season, corn is treated with Callisto once. The waiting period at a rate of suspension consumption of 0.15-0.25 l / ha is 2 calendar months. The protective effect time depends on the following factors:

  • weed growth phases;
  • weather, rain immediately after treatment reduces the effect of herbicide application, precipitation does not affect the result if more than an hour has passed since spraying;
  • weed species;
  • concentration and consumption of the working mixture.

Preparation of working solution

The effectiveness of the liquid mixture is increased by adding the drug "Corvette Zh" - 0.5 l of adjuvant is consumed per 100 l volume.

Corvette improves the adhesion, sprayability, absorption of the herbicide solution.

Algorithm for preparing the solution "Callisto":

  • tank ½ filled with water;
  • start the stirrer;
  • infuse the norm of the drug;
  • add water.

Until the components are dissolved, the mixture is stirred. The finished solution is used immediately after mixing.

Instructions for using the ready solution

Corn is processed in the morning when there is no dew or rain. With wind strength up to 3 m / s. The day before, the sprayer is inspected. It consists of several operations. Evaluation of the cleanliness of the tank, the serviceability of the atomizers. Adjustment of uniform liquid supply. The volume must match the calculated flow rate.

The maximum result in the destruction of weeds is achieved at the stage of development of weeds:

  • for annuals - 2-3rd leaf;
  • for perennials - rosette 5-8 cm.

In order for the mesotrione substance to reach growth points faster, harmful vegetation is abundantly moistened with working fluid.

Precautions

There is no harm to he alth when using a herbicide if the recommended safety precautions are followed. The product is classified as hazard class 3 for humans, hazard class 3 for bees.

Mechanized work can be planned on the herbicide-treated field after 3 days.

Restrictions to be observed when applying:

  • cultivate territories located in fishery zones;
  • forbidden to use in dachas, vegetable gardens;
  • cannot be sprayed by aeronautical method.

Phytotoxicity of the drug

There is no risk of phytotoxicity if the herbicide is sprayed in accordance with the rates specified in the instructions.

Compatible with other pesticides?

"Callisto" is used in tank mixes. This allows you to expand the spectrum of action of the herbicide. Before preparing a working solution, a compatibility test of all components is carried out. Before use, study all the instructions that come with the companion preparation. Their terms of application must match.

Milagro (0.75-1 l/ha) is mixed with Callisto (0.15-0.2 l/ha) to kill cereals. Against perennials that reproduce by root offspring, the herbicide is mixed with Banvel:

  • consumption of the first agent 0.15-0.2 l/ha;
  • consumption of the second product 0.1-0.15 l/ha.

Insecticides containing organophosphorus compounds, thiocarbonates are not used on corn before and after spraying the crop with Callisto herbicide. Pause between treatments is 7 days.

Terms and conditions of storage

The herbicide is sold in cans. It is effective for 3 years. The term is considered from the date of issue, if the original packaging is not opened. Indoor conditions:

  • dry air;
  • lower temperature limit -5 °C;
  • upper temperature limit +35 °C.

Analogues

Syngenta produces the Sumaro herbicide. This is an analogue of Callisto in terms of the active substance. The suspension of mesotrione contains 480 g/l. Apply a remedy against broad-leaved weeds. The preparation works in the temperature range of 8-25 °C. Corn is sprayed with a solution of "Sumaro" in the phase of 3-8 leaves.

"Mesokron" - the second analogue of "Callisto" in terms of the active substance. In it, the concentration of mesotrione is 480 g / l. The drug is used to treat corn from dicotyledonous and cereal weeds. Like Callisto, Mesocorn has a soil effect, inhibits the development of the 2nd wave of weeds.
