Abstract:
In the conditions of the
central area of Moldavia, losses in
quantitative and qualitative wheat
productions are determinated by pathogen
agents which are transmitted by groundside
and seed, like Fusarium sp. and Tilletia
tritici, but also by some soil pests like the
wire worms (Agriotes sp.) and the
hunchback bug (Zabrus tenebrioides).The
prevention or decreasing of the attacks was
achieved in the conditions of the
Agricultural Research and Development
Station (ARDS) of Secuieni, Neamţ county,
Romania, by the chemical treatment of the
seed using a range of insectofungicides
(Yunta 246 FS, Nuprid Max, Austral Plus
Net, Lamardor + Gaucho, Yunta Quatrro,
Yunta Succesor, Alios 300 FS). The
experienced insectofungicides insured a
good plant protection against the attack of
Agriotes sp., the plants frequency at the
untreated variant was 6.37% and between
0.77% and 1.42% at the treated variants,
and against Zabrus tenebrioides species, the
frequency of damaged plants at the
untreated variant was 1.76%, compared
with 0.16% and 0.54% at the treated
variants. Differences statistically insured
were registered also in the attack produce by
Fusarium sp. and Tilletia tritici, between the
treated variants with the experimented
insectofungicides and the untreated variant.
The experienced insectofungicides in the
seed treatment haven’t influence in the
negative way on the seed germination,
plants growth, development of plants root
system as well as plants fraternally; between
the treated variants and the untreated variant
have been registered differences statistically
insured in all the made biometric
observations. The good protection, insured
by the experienced insetofungicides, had a
positive influence on the wheat production
to hectare which was 4852 kg/ha in the
untreated variant and between 5225 kg/ha
and 5930 kg/ha in the treated variants; the
production differences between the treated
variants and untreated variant were
statistically insured.
