Express 75% VG 0,5 kg

Mechanism of action

Express 75 VG — a systemic herbicide designed for post-emergence control of annual and perennial dicotyledonous weeds, especially certain problem, in crops of sunflower hybrids P63LE10, РR64E83 and РR64Е71 company “pioneer”.

In composition of Express 75 V. G. is well known for the active substance tribenuron-methyl, which quickly (within 30 hours) stops the division of cells sensitive weed species, resulting in the growth of weeds is blocked, they do not compete with the culture for the nutrients, water and light. Visible symptoms appear

after 508 days, and complete destruction of weeds occurs within 10025 days. Warm and humid weather increases the speed of action of the herbicide, while cool and dry slows it down.

The rate

Express V. 75 g. used in normal 30-50 g/ha once, or separately (30+20 g/ha) on hybrid PR64E83 and normally 25-30 g/ha once on the hybrid PR64E71.

It is recommended to add the surfactant Trend 90. Under the influence of the surfactant Trend 90 by reducing the surface tension of the working solution and reduce the rate of evaporation is increased absorption of the herbicide by the weed leaves.

Utilization rate PAIRS Trend 90 – 100 ml per 100 l of spray solution.

PAIRS Trend 90 is added in the presence of ragweed and weeds, which are poorly wetted (field weed, sow Thistle, quinoa) and to enhance the effect of the dry conditions.

 

Selectivity

Sunflower hybrids P63LE10, РR64Е83 and РR64Е71 company “pioneer” is created by conventional breeding by backcrossing the original lines that have natural resistance to the herbicide

Express 75 V. G. Genetic resistance of the hybrid to Express 75 VG allows you to use the drug in a wide range: from 2 to 8 leaves of sunflower in the early stages of weed development.

The use of Express 75 VG on other varieties and hybrids of sunflower, resistant to the action of the drug, leads to their damage and even death.

 

Control of annual dicotyledonous weeds

Express® 75 VG provides maximum efficiency when used at early stages of weed development (608 leaves of annual species), actively vegetate.

It is important to monitor the stage of weed development to determine the most effective period for use of Express 75 V. G. it is also Important that weeds are actively vegetabale and was not under stress due to drought or cold.

Control perennial weeds

Express 75 VG provides a unique control key for the growing zone of sunflower perennial dicotyledonous weeds – Thistle pink and yellow field.

The best control of this weed pink – phase sockets – the beginning of the formation enerating escape that, as a rule, coincides with the stage 406 of the leaves of sunflower plants.

Through the use of the herbicide Express V. 75 g. achieved a significant increase in the effectiveness of the program of protection of sunflower against malicious weeds — ragweed (if its on

the time of spraying), Datura Stramonium, Xanthium ordinary, grcav, quinoa white, kanatnikov Theophrastus, rape, Thistle.

 

Special recommendations: control of volunteer sunflower P63LE10, PR64E83 and PR64E71

It is known that the fallen sunflower may appear in subsequent years in other cultures of crop rotation. Stimulate early germination of sunflower hybrids P63LE10, РR64E83 and РR64Е71 company “pioneer” beginning next after sowing, is resistant to the action of herbicides – inhibitors of the enzyme aselectedunits (ALS inhibitor).

To prevent the spread of resistant Express V. 75 g of sunflower it is necessary to observe the special recommendations for the control of resistant sunflower to sowing the next crop.

-It is necessary to use herbicides other than ALS, mechanism of action.

-Are herbicides applied alone and in tank mixtures with herbicides with an ALS mode of action. It is a mixture of herbicides will provide excellent efficacy against volunteer this sunflower.

-For control of fruit drop resistant Express V. 75 g sunflower seeds in subsequent crop rotation are recommended to use

on grain crops:

Granstar gold, Calibre®, Super Ally®, Lauren® in tank mixtures with herbicides on the basis of fluroxypyr, dicamba, 2,4–D, 2M–4X;

on corn:

Titus, Basis, harmony in tank mixtures with herbicides of the hormonal group (2,4–D, dicamba). The herbicide Task of tank mixes is not required.

_ It is necessary to provide spatial isolation of 1500 m for areas intended for seed crops or lots of hybridization of sunflower, from the sunflower crops, tolerant to Express® 75 VG
