Instructions for the use of the herbicide Callisto, mechanism of action and consumption rate

Callisto is a specialized herbicide. It is used for processing corn fields. The new protective equipment is produced by Syngenta (Switzerland). Its products (fungicides, insecticides, herbicides) are used by farmers and agro-industrial enterprises.

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

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

The drug is produced in liquid form - KS (suspension concentrate). Packaged in 5 liter containers. The concentration of mesotrione in the herbicide is 480 g / l. Spectrum of action "Callisto":

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

The mechanism of action of the herbicide

Treatment with a selective, systemic, post-emergence herbicide does not harm corn. They can spray the culture in the phase of the 8th leaf. Due to the mild effect of the drug on young plants, weed control works are 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 growth points;
• the entire aboveground part becomes light;
• tissues die off.

Weed plants completely die in 1-2 weeks.

Positive and negative sides

The herbal preparation Callisto has a number of advantages. It is used in tank mixes. It kills weeds that are not affected by other herbicides. Treatments are carried out at different stages of development of corn and weeds. Using Callisto eliminates the re-emergence of weeds:

• bindweed;
• sow thistle;
• cable car;
• ambrosia;
• other cereal, dicotyledonous weeds.

In heavily weedy conditions, Callisto cannot cope with all types of weeds. It is used in combination with other means. He works most effectively with the drug "Milagro". Their mixture destroys 90-95% of weeds in the 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 suspension consumption rate of 0.15-0.25 l / ha is 2 calendar months. The protection time depends on factors:

• weed growth phases;
• weather, rain that has passed immediately after treatment reduces the effect of the application of the herbicide, precipitation does not affect the result if more than an hour has passed since spraying;
• type of weed vegetation;
• 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 liters of adjuvant are consumed per 100 liters.

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

Algorithm for the preparation of the Callisto solution:

• the tank is ½ filled with water;
• start the mixer;
• pour in the rate of the drug;
• add water.

The mixture is stirred until the components are dissolved. The ready-made solution is used immediately after mixing.

Instructions for using the ready-made solution

Corn is processed in the morning when there is no dew or rain. With a wind force up to 3 m / s. On the eve of the revision of the sprayer. It consists of several operations. Evaluation of the cleanliness of the tank, serviceability of the sprayers. Adjusting the uniform flow of fluid. The volume must correspond to the estimated flow rate.

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

• in annuals - 2-3rd leaf;
• for perennials - a socket of 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 health hazard when using the herbicide if the recommended safety precautions are followed. The product is assigned to the 3rd hazard class for humans, to the 3rd hazard class for bees.

After 3 days, mechanized work can be planned on the field treated with herbicide.

Restrictions that must be observed when applying:

• to process the territories located in the zones of fishery purposes;
• it is forbidden to use in summer cottages, vegetable gardens;
• can not be sprayed by aviation method.

Phytotoxicity of the drug

There is no risk of phytotoxicity if the herbicide is sprayed in accordance with the rates indicated 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 the 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 coincide.

Milagro (0.75-1 l / ha) is mixed with Callisto (0.15-0.2 l / ha) for the destruction of cereals. Against perennials propagating by root suckers, the herbicide is mixed with Banvel:

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

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

Terms and conditions of storage

The herbicide is sold in canisters. It is effective for 3 years. The term is counted 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.

Analogs

Syngenta produces Sumaro herbicide. This is an analogue of "Callisto" in terms of the active substance. The suspension of mesotrione contains 480 g / l. Apply an agent against broadleaf weeds. The drug works in a temperature range of 8-25 ° C. The "Sumaro" solution is sprayed on corn in the phase of 3-8 leaves.

"Mesocron" is the second analogue of "Callisto" in terms of active substance. It has a mesotrione concentration of 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 second wave of weeds.
