ABSTRACT 

This article investigates the insecticidal activity of the chemical preparation Antikolorad Max, sus.k., against major 

wheat pests such as harmful bugs, slimy worms, wheat thrips, and grain aphids. According to the results of the 

experiment, when this preparation was applied at a rate of 0.1-0.15 l/ha, it demonstrated a biological efficiency of 88.6-

92.5% against harmful bugs, 91.6-94.8% against slimy worms, 89.4-95.8% against wheat thrips, and 89.4-93.1% against 

aphids 14 days after application. 

 

KEYWORDS

INTRODUCTION

Today, one of the critical issues that humanity needs to

ranks first among cereal crops in terms of nutritional 

value for humans, accounting for 35% of their food 

requirements. However, the main reason for the 

decline in wheat yield is the damage caused by pests 

that feed on wheat, resulting in significant yield losses. 

Among the wheat pests, six species of grain aphids, 

four species of harmful bugs, six species of thrips, and 

one species of slimy worms are known to cause 

significant damage. 

One of the main pests widespread in all wheat-growing 

regions of Uzbekistan is the harmful bug. Adult bugs 

emerge from hibernation in March-April and initially 

damage the central leaf part of the plant, followed by 

the grain part, causing the whole plant to wilt. The 

germination rate of grains from fields infested with 

harmful bugs decreases by up to 50%. Additionally, 

wheat thrips can reduce yields by 5-13%. Adult thrips 

attach to the upper leaf sheath during the stem 

elongation phase of wheat, causing significant 

damage. Thrips larvae can lead to up to a 20% yield loss. 

Scientists have identified 29 species of aphids that 

damage wheat yields. During the growth period of 

autumn wheat, aphid epidemics cause damage by 

sucking cell sap from the leaves. Yield losses due to 

aphids range from 7.9% to 34.2%. Some authors have 

noted that timely planting of wheat can reduce the 

damage caused by aphids. The slimy worm (pyavitsa) 

Lema melanopus L. (order Coleoptera, family 

Chrysomelidae) is a dangerous pest that significantly 

damages wheat, barley, and other cereal crops. Its 

larvae undergo four molts to reach adulthood, with the 

fourth stage larvae causing the most damage. 

Given the above, it is crucial to find effective control 

measures against the main wheat pests to preserve 

wheat yields. For this purpose, we conducted research 

on the effectiveness of the chemical preparation 

Antikolorad Max, sus.k., against the main wheat pests. 

METHODS 

To determine the insecticidal activity of chemical 

preparations against the main wheat pests, 

experiments were conducted in 2024 on a 7.5-hectare 

field of the "Soxibkor agro" farm in Tayloq district, 

Samarkand region. 

The timing of pest emergence and population counts 

were conducted according to the methods of Polyakov 

et al. (1984), Osmolovsky G.E., and Bondarenko N.V. 

(1978). Pest counts were performed during the stem 

elongation and heading phases of wheat. A logarithmic 

scale was used to determine the number of pests per 

plant and the population density in the wheat field. 

The degree of leaf damage was assessed using the 0-5 

scale of Stamenkov, S., and Pankov, L. (1991) and the 

methods of Rouag N. et al. (2012). The insecticidal 

activity of the preparations in field conditions was 

determined using the methodological guide of 

Khojayev (2004), and biological efficiency was 

calculated using Abbott's formula (1925). 

Counts were performed on days 3, 7, and 14 after 

treatment. Experiments were conducted in three 

replicates for each variant, including control 

(untreated). A tractor-mounted sprayer was used to 

apply the working solution at a rate of 300 liters per 

hectare. 

RESULTS AND DISCUSSION 

Field trials were conducted to determine the 

effectiveness of Antikolorad Max, sus.k. (Imidacloprid 

+ lambda-cyhalothrin) against major wheat pests at 

rates of 0.1-0.15 l/ha (Figure 1).

demonstrated a biological efficiency of 78.7% on day 3, 

85.0% on day 7, and 88.6% on day 14 at a rate of 0.1 l/ha

89.2% on day 14. In the control variant, the number of 

pests increased from 8.1 to 14.1 per plant over 14 days. 

Against slimy worms, Antikolorad Max, sus.k. 

demonstrated a biological efficiency of 60.0% on day 3, 

82.2% on day 7, and 91.6% on day 14 at a rate of 0.1 l/ha. 

At a rate of 0.15 l/ha, the biological efficiency was 62.2% 

on day 3, 89.5% on day 7, and 94.8% on day 14. The 

standard preparation Borey, 20% sus.k., showed 62.0% 

on day 3, 86.2% on day 7, and 93.2% on day 14.

worms, 89.4-95.8% against wheat thrips, and 89.4-

93.1% against aphids 14 days after application. 

Therefore, Antikolorad Max, sus.k., at a rate of 0.1-0.15 

l/ha, can be considered an effective chemical control
