Combating agricultural weeds is an eternal topic. Chemists are trying to provide gardeners and field farmers with reliable and effective means.
Among them, Milagro, a herbicide that cannot be used without first reading the relevant instructions, confidently occupied its niche.

Active ingredient and preparative form
The study of instructions for the use of the herbicide Milagro begins with clarifying the question of what substance in its composition has the desired effect on plants that prevent the normal development of maize.
It is called nicosulfuron, a chemical class of sulfonylurea. The drug is available in the form of a suspension concentrate (40 g / l), sold in 5-liter cans. It is possible and other (liter, for example) packing with the content of nikosulfuron 240 g / l.
Activity spectrum
This substance systemically selectively inhibits and destroys in the fields,where maize is grown (for silage and grain), weed cereal (perennial and annual) plants, as well as a number of dicotyledonous weeds.
- humay;
- highlanders;
- Galinsog small-flowered;
- dope
- star wheel is average;
- white mary;
- bluegrass;
- forget-me-not;
- wild oats;
- black hairy;
- Rosicka;
- bristle
Benefits
The advantages of this herbicide for corn are determined by its high adaptability, the result of which are:
- The selectivity of action, in no way harming the culture itself.
- Efficacy against weeds that are not sensitive to other substances (wheatgrass, gumai, other harmful plants, germinating from seed and rhizomes).
- Let's apply at all stages of growth of corn (except pre-emergence).
- Comfortable simplified procedure for obtaining a working solution of the desired quality (due to additives from surfactants).
- Quickly breaks up, hitting the ground.
Mechanism of action
As already mentioned, Milagro acts selectively - even its double dosage in the working mixture will not harm the corn.
At the same time, a preliminary test for phytotoxicity of the fields where hybridization is planned will not hurt.
Efficiency in relation to weedy objects appears twice:
- first, their development is inhibited and completely stopped;
- then, after some time, the weeds die without a trace.
The peculiarity of the action of this herbicide is also the fact that only plants which shoots appeared at the time of application are exposed to it. Therefore, to control weeds that have appeared after chemical exposure, inter-row cultivations are carried out (one and a half to two weeks). The same work is not allowed at least a week before spraying.
When and how to spray
The Milagro herbicide is a post-emergence drug, but flexibility can be shown when choosing the timing of the spraying.
For the daily period, airlessness is important (so that the drug does not get on crops grown nearby) and part of the daylight hours — treatment takes place in the morning or evening.
Seasonal specifics appear with the complex consideration of all factors:
1. At what biological stage of development are the weeds (it is desirable that this be when they are actively vegetating, and the warming up of air is in the range from 15 to 30 ° C).
Details of the preparation of the working solution:
- The process is carried out right before the spraying procedure.
- Half-tank is filled with clean water.
- The agitator is turned on and, as the remaining half of the capacity is filled with the preparation, the consumption of which you have already calculated, continues to work.
- the next substance is not added until the previous one is completely dissolved;
- if there is a component in a package that also dissolves in water, then it is added first.
Action speed
The drug is considered high-speed, you can count on:
- stopping the growth of harmful plants after 6 hours;
- their final death - in a week.
- unfavorable weather conditions (at the time of spraying and the initial period of action of the substance);
- the weeds have reached the peak of their physiological state (or are at the stage of confident achievement).
Period of protective action
Protection is valid for 1.5-2 months. More precisely, the dates can be calculated (also approximately) already during the field season, they will be affected by:
- weed plant species;
- phasing in the development of weeds;
- weather in the period after herbicidal treatment.
Compatibility
The incomplete list of pesticides compatible with Milagro is quite large: Banvel; EDC; BP; Dual Gold; Callisto; Karate Zeon; CE; ISS; SC; JV Compatibility is expressed not only in the features of the chemical interaction, but also in the timing of the application.
- Burns of cultural foliage can be caused by a Milagro tank mixture with a laitagran and a bazagran.
- Sharing with herbicides created on the basis of 2,4-D will not lead to the effective eradication of grass weeds, because there is antagonism in their control between the weed remedies.
Crop rotation after processing
The variability of crop rotation after the application of Milagro is wide: in the next field season, the sowing of any crops is allowed. However, there are some features that must be taken into account by business executives:
- The considered herbicide has a tendency to very rapid degradation on soils with an acidic reaction less than pH7, if they are saturated with biologically active microorganisms, warm up well and hold moisture. Then, if necessary, you can re-seed the field either in spring - again with corn (you can still have soy, but in this case plowing is needed), or in the fall, but with winter wheat or barley.
- Attention should be paid to the weather conditions in which alkaline (pH> 8) land plots were located before the subsequent sowing campaign - drought during this period can adversely affect the development of the next planted crop.
For the latter case, it is necessary to know the level of negative perception by the garden and field plants of a given herbicide (from highest to lowest):
- sugar beet;
- tomatoes;
- buckwheat;
- wheat;
- barley;
- rape;
- oats;
- soy.
Shelf life and storage conditions
The drug is valid for three years from the date of manufacture (when buying, pay attention to the inscription on the package). In the original packaging it should be stored (it should be tightly closed). Temperature drops are allowed from -5 to + 35 ° С. The room must be dry.
Good corn can be grown by protecting it in time from weedy pests. Milagro will help you.
